The spring of a spring balance is 7.0 cm long when there is no weight on the balance, and it is 85 cm long with 9.0N hung from the balance. How much work is done in stretching the spring from a length of 80 cm to 10.0 cm? The amount of work done in stretching the spring is N cm. (Simplity your answer)

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the falcrum how long was the seesaw on Andy's side?

1. A uniform stick can be balanced on a knife edge 10 cm from one end when a load of 200 N is hung from that end. When the knife edge is moved 5 cm further from the end, the 200 N load has to be moved to a point 8.75 cm from the knife edge to obtain a balance. Find the length of the stick and its weight.
Assume the image below is your arm and you are lifting a 15 lb weight. your arm is now at a 50-degree angle to your body. The force from the muscle is vertical. The weight of your arm is 5 lbs. dbiceps is 2cm and dball is 6cm. Please draw a free body diagram of the arm at that 50-degree angle with the forces. What is the force that the muscle puts on the arm? What is the force from the muscle if the weight is all the way up?
