Torque in wheelbarrow, bicycle gears, and steel girder

[nsingh947]

apply the concept of torque to explain how a wheelbarrow allows you to transport a heavy load with a lifting force than the weight of the load

a 10-speed bicycle has five gears on the rear wheel. when the bicycle is in first gear, is the chain on the gear with the largest radius or the smaller radius? use the concept of torque to explain your answer

dana and loren are carrying a steel girder. Dana is holding the girder at the end while loren is not. who is exerting the greater force on the girder? justify your answer using the concept of torque
