A cord can withstand 3,000 N of tension before it snaps. If a moving company
uses this chord to hoist a 200 kg piano with an acceleration of 5.00 m/s2, will the
cord snap? *
a. No, the cord will not snap because there is 1,000N of force from the piano
b. Yes, the cord will snap because there is 5,000N of force from the piano
c. Yes, the cord will snap because there is 10,000N of force from the piano
d. No, the cord will not snap because there is 500N of force from the piano

A5 foot by 5 foot box culvert is buried 6 feet beneath the surface of the ground. a crosssection of this very long culvert (into and out of the page) is illustrated below. assume that the soil in which the culvert is buried has the following properties: jt = 120 pcf, w = 12%, ko = 0.50, ka = 0.33, and kp = 3.00. calculate the total horizontal force per unit length of culvert (fh) felt on one of the vertical faces of the culvert.

Suppose that a cylindrical tank 6 meters high with a radius of 2 meters is filled to the rim with water. the tank is buried so that the top of the tank is 1 meter below ground level. the space above the tank is not filled with water. calculate how much work needs to be done by a pump to pump the water out of the tank up to ground level. (the water weighs 9,800 newtons per cubic meter.)
