How can you tell if you need to solve the problem as if the effort is applied at the axle or applied at the wheel if not stated in the problem?
When an axle is exerted, the force on the system decreases while the torque on the axle increases as a result of the effort, which results in
In science, what exactly is a force?
In science, "force" refers to a certain concept. It is quite acceptable to refer to a force of this level as a push or a pull. It's incorrect to say that an object "has in it" or "contains" a force. A force is experienced by one thing from another. The concept of a force makes no distinction between living creatures and inanimate objects. Force is defined as a push or pull that causes the body it is acting on to accelerate. The unit of force in the SI is the Newton.

10) A roller coaster has a circular loop of radius 5.0 m. You go around at the minimum speed.
How fast will you be moving at the bottom?
What is your acceleration? (in m/s2, in g’s)
How does this feel? Where else have you felt this effect?
Draw a Force Diagram at the bottom.
This is dangerous. What should the radius be at the bottom, so that you only feel 2 g’s?
.
Explain why these loops have the shape that they do.
Answer:
1) The speed of the roller coaster at the bottom is approximately 15.65 m/s
2) The acceleration of the roller coaster at the bottom is 6·g's
3) The high acceleration is 6 times the force of the weight of the passengers
The high acceleration can cause gravity induced loss of consciousness
4) Please find attached a force diagram of the forces at the bottom of the roller coaster created with Microsoft Visio
5) For the acceleration at the bottom to be 2·g's the radius of the rollercoaster at the bottom should be 25 meters
5) The radius at the bottom of roller coasters are increased to reduce the normal force felt by the passengers as they pass the bottom of a circular roller coaster
Explanation:
1) The given parameters are;
The radius of the roller coaster, r = 5.0 m
The speed of the roller coaster = Minimum = 0 m/s
The shape of the roller coaster's path = Circular loop
Therefore, the maximum height of the roller coaster, h = The diameter of the of a circular path of the roller coaster, d = 2 × r = 2 × 5.0 m = 10.0 m
∴ h = 10.0 m
The minimum speed is f=given by the following equation;
[tex]F_N = \dfrac{m \cdot v^2}{R} - m \cdot g = 0 \ (At \ the \ top \ of \ the \ roller \ coaster's \ path)[/tex]
Therefore, we have;
[tex]\dfrac{m \cdot v^2}{R} = m \cdot g[/tex]
From which we have;
v = √(R × g)
Where;
R = The radius of the path of the roller coaster = 5.0 m
g = The acceleration due to gravity = 9.8 m/s² = constant
By plugging in the values of the variable, 'R', and the constant, 'g', we get;
v = √(5.0 m × 9.8 m/s²) = 7 m/s
The minimum speed of the roller coaster, v = 7 m/s
The speed of the roller coaster at the bottom is given by the conservation of energy formula as follows;
The energy at the top of the roller coaster = The energy at the bottom of the roller coaster
∴ The total mechanical energy of the roller coaster, M.E., is constant and at the top, [tex]M.E._{top}[/tex], is given as follows;
[tex]M.E._{top}[/tex] = 1/2·m·v₁² + m·g·h₁
At the bottom, the total mechanical energy is given as follows;
[tex]M.E._{bottom}[/tex] = 1/2·m·v₂² + m·g·h₂
Where;
v₁ = The velocity of the roller coaster at the top = 7 m/s
h₁ = The height of the roller coaster at the top = 10 m
v₂ = The speed of the roller coaster at the bottom
h₂ = The height of the roller coaster at the bottom = 0 m
g = The acceleration due to gravity = 9.8 m/s² = Constant
By plugging in the values, we get;
M.E. = [tex]M.E._{top}[/tex] = [tex]M.E._{bottom}[/tex]
∴ 1/2·m·v₁² + m·g·h₁ = 1/2·m·v₂² + m·g·h₂
1/2 × (7 m/s)² + 9.8 m/s² × 10.0 m = 1/2 × v₂² + 9.8 m/s² × 0 m
122.5 m²/s² = 1/2 × v₂²
∴ v₂² = 2 × 122.5 m²/s² = 245 m²/s²
v₂ = √(245 m²/s²) = 7·√5 m/s ≈ 15.65 m/s
The speed of the roller coaster at the bottom, v₂ ≈ 15.65 m/s
2) The normal force on the car at the bottom of the roller coaster is given as follows;
[tex]F_N = \dfrac{m \cdot v_2^2}{R} + m \cdot g = m \times \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
Force, F = Mass, m × Acceleration, a
∴ F = m×a
Therefore, the acceleration at the bottom, 'a' by comparison of the general equation for force, 'F', and the normal force, [tex]F_N[/tex], is given as follows;
[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
Plugging in the values for 'v₂²', 'R', ang 'g', gives;
[tex]a = \left(\dfrac{ v_2^2}{R} + g \right ) = \left(\dfrac{ 245}{5} + 9.8 \right ) = \left(49+ 9.8 \right ) = (5 + 1) \times 9.8 = 6 \times 9.8 = 6 \times g[/tex]
a = 6·g = 58.8 m/s²
3) The high acceleration will lead to a very high normal force (equal to 6 times each of their weight) experienced by the passengers with a force
The high acceleration is dangerous and can lead to gravity induced loss of consciousness since it is more than 3·g's
4) Please find attached the force diagram at the bottom of the roller coaster created with Microsoft Visio
5) For the acceleration at the bottom to be 2·g's, we have;
[tex]a = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
At a = 2·g, we have;
[tex]2 \cdot g = \left(\dfrac{ v_2^2}{R} + g \right )[/tex]
[tex]\therefore 2 \cdot g - g = g = \dfrac{ v_2^2}{R}[/tex]
[tex]R = \dfrac{ v_2^2}{g} = \dfrac{245}{9.8} = 25[/tex]
R = 25 m
The radius at the bottom of the roller coaster should be 25 meters so that only 2·g's is felt
5) The shape of the roller coaster has an increases the radius at the bottom so as to reduce the acceleration of the car

Why are the main cables of the Golden Gate Bridge made of numerous smaller cables?
Answer:
The main cables of the Golden Gate Bridge are made of numerous smaller cables because by combining several thousand in number of smaller cables, each having a diameter which is approximately the diameter of a pencil, into the required cable diameter dimensions, the flexibility, strength, resistance to cracking, rotation resistance, crushing resistance and fatigue resistance of the main cables are increased, and failure of a few strands in a multi-stranded cable is more likely to be detected before catastrophic failure takes place than in a single cable
The properties of strength and flexibility that the cable provides are required so that the bridge can better cushion the seismic turbulence of the water and strong wind energy at the bay of San Francisco, the location of the bridge

A gear train has a ratio of 40/24 and the driving gear is turning 100 RPM.
What is the speed of the driven gear in RPM?
Answer:
S2 = 60 RPM.
Explanation:
Given the following data;
Gear ratio = 40/24 (T2 = 40 and T1 = 24).
Speed of driving gear = 100 RPM
To find the speed of the driven gear;
Mathematically, gear ratio in terms of speed (RPM) is given by this formula;
[tex] S_{1} * T_{1} = S_{2} * T_{2} [/tex]
Where;
S1 represents the speed of the driver gear.S2 represents the speed of the driven gear.T1 represents the number of teeth of the driver gear.T2 represents the number of teeth of the driven gear.Substituting into the equation, we have;
[tex] 100 * 24 = S_{2} * 40[/tex]
[tex] 2400 = 40S_{2} [/tex]
[tex] S2 = \frac {2400}{40} [/tex]
S2 = 60 RPM.
Therefore, the speed of the driven gear is 60 revolutions per minute.

I. Inclined plane: GPE to KE.
II. Screw: KE to GPE.
III. Wheel and axle: GPE to KE.
IV. Lever: GPE to KE.
V. Wedge: GPE to KE.
VI. Pulley: GPE to KE.
Explanation:
A simple machine can be defined as a type of machine with no moving parts but can be used to perform work.
Basically, a simple machine allows for the transformation of energy into work. The six simple machines are;
I. Inclined plane: gravitational potential energy to mechanical energy (kinetic energy). It is set at an angle and then used to lift an object.
II. Screw: kinetic energy to potential energy. It is held in position and then used to tighten two or more objects together.
III. Wheel and axle: gravitational potential energy to mechanical energy (kinetic energy). It comprises of two circular objects which aids in the motion of an object such as a car.
IV. Lever: gravitational potential energy to mechanical energy (kinetic energy). It comprises of a pivoted bar at a fixed point (fulcrum) that allows it to be used for lifting heavy objects.
V. Wedge: gravitational potential energy to mechanical energy (kinetic energy). It can be used to split objects into halves.
VI. Pulley: gravitational potential energy to mechanical energy (kinetic energy). It is made up of a wheel and rope which allows force to be multiplied such as in a drawing well.
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
