Work can only be done when the force applied to an object casues the object to move. Timmy and Tommy are trying to move the roll of hay.
They push and push but the hay doesn't budge. Timmy and Tommy finally
give up because they are absolutely worn out. Did Timmy and Tommy do
any work? *
Please help

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.
