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...

In this case both top and bottom supports of the PVC pipe are fixed. There is only one lever arm at the center of the pipe where torque is caused by applying weights of 5 N on each side of the hanger. Place dial gage at the point where load is applied to measure the deflection caused by it. After making the initial reading zero on the...

Exploration 2.2 For this Exploration, find a door at home. First apply a force perpendicular to a line through the pivot point (the door hinge) and the point of application. In other words, apply a force perpendicular to the door. Depending on the mass of the door, the force applied may not need to be very large. Just make sure you use the same force for all portions of this exercise. Then apply the force at an angle. Is the...
