please help me?
1. Explain how you can exert a large force on an object without doing any work.
2. Describe how a ramp can make lifting a box easier without changing the amount of work being done.
3. A short ramp and a long ramp both reach a height of 1m. Which one has a greater mechanical advantage?
4. A bus driver applies a force of 55 N of force on the steering wheel which in turn applies 132N of force on the steering column. What is the machanical advantage of the steering wheel?
5.An outboard engine on a boat can do 1 x 10^6 J of work in 50sec. Calculate its power in watts and convert the the answer to horsepower.
1.) You only have work if the object is moved. You can exert a large force if that is required to keep the object in one place.
Ex: Holding a child
If you hold a child, you are exerting an upward force on the child which is equal to 100% of the child's weight. However, the child does not move, so no work is being done. (But your muscles will tell you that you are exerting a force.)
