A bicycle mechanic is checking
a road bike's chain. He applies force F = 30 N to a pedal at the
angle shown in (Figure 1) while keeping the wheel from rotating.
The pedal is 17 cm from the center of the crank; the gear has a
diameter of 16 cm.

I've been having some trouble figuring out where to start on
this maths task:
Investigate how the gears of a multi-speed bicycle allow
a rider to increase torque with reduced effort:
You will need to obtain relevant measurements, such as
the length of the moment arm for each of the gears. You may use
research or collect your own measurements.
Consider your assumptions, which should be reasonable
(eg, pedal force applied by the rider).
Simulate the relationship...

Q3: In the figure, a constant horizontal force of magnitude 16 N applies to a wheel of mass8 kg and radius 0.4 m from its center of mass. The wheel rolls smoothly on the horizontal surface. If the rotational inertia of the wheel is 0.85 kg.m2, find the a) linear and angular acceleration of the wheel, b) direction and magnitude of the frictional force on the wheel? Answer: a) a = 1.2 in/s2 and α = 3 rad/s. b) 6.4...

A bicycle wheel has four firecrackers attached to it on opposite ends of the wheel's diameter, as shown in the figure to the right. When the firecrackers are lit, they release heated gas away from their front ends. The bicycle wheel is pivoted against a wall by its center of mass and is free to spin. a. Which way will the bicycle wheel spin when the firecrackers are lit? Explain using the torque right hand rule. b. What is the...

An athlete is measuring the force by their flexor muscle by pulling a rope horizontally at a constant force. While pulling the rope the muscle applies a force on the forearm an angle of 71° as shown in the diagram. While keeping your forearm completely vertical, the tension in the rope is at 185N. The athlete's muscle is attached to the forearm 5 cm from the elbow joint and that the weight of your forearm is 22 N with a...
