Prisms Chains
A Couple of Calculus Questions?
1. Assume that 10 ft*lb of work is required to stretch a spring 1 ft beyond its natural length. What is the spring constant? (I know this problem is easy but my answer comes out to half of the correct answer.)
2. A vat (triangular prism) contains water to a depth of 2m. Find the work required to pump all the water to the top of the vat. [Use 9810 N/m^3 as the weight density of water] (Dimensions of the tank are height=3m, length=6m, and base or width=4m)
3. A 100-ft length of steel chain weighing 15 lb/ft is dangling from a pulley. How much work is required to wind the chain onto the pulley?
4. A swimming pool is built in the shape of a rectangular parallelepiped 10ft deep, 15ft wide, and 20ft long. A one-horsepower moto can do 550 ft*lb or work per second. What size motor is required to empty the pool in 1 hour?
Please show work.
The answers are as follows: yes, eleventynine, pudding, and hello.
