15 Two workers load identical refrigerators into identical trucks by different methods. One worker has the refrigerator lifted upward onto the back of the truck, which is 1.5 m above the ground. The other worker uses a ramp to slide the refrigerator onto the back of the truck. The ramp is 5.0 m long, and raises the refrigerator 1.5 m above the ground. The amount of work done by both workers is the same: 1800 J. What are the magnitudes of the forces each worker must exert to load the refrigerators?

Trina is a gym goer with a leg length of 84 cm. Suppose that she is in the gym doing straight leg raising with 10 Ib weights. Compute for the force that the muscle should exert in order to (1) maintain it in the position and (2) lift the weight up given that the distance of the effort (muscle) from the joint is 54 cm, distance of the weight is 80 cm, and the COM is 45 cm from the joint. Questions: 1. Draw the free body diagram for straight leg raise. 2. What is the muscle responsible for straight leg raise? 3. What is the fulcrum? 4. What is the effort? 5. What is the resistance?
