Frost wedging breaks apart a large rock measuring 12 m long by 12 m wide by 2 m high into four equal pieces measuring 6 m long by 6 m wide by 2 m high. How much greater, in m2, is the total surface area of the four pieces compared to that of the original rock?
Homework Answers
The surface area of the bigger piece of rock = 2(12*12)+ 2(12*2)+ 2(2*12) = 384 m2
The surface area of one of the smaller pieces = 2(6*6)+ 2(6*2)+ 2(2*6) = 120m2
The surface area of four such pieces = 4*120 =480m2
The total surface area of the four pieces compared to that of the original rock is 1.25 times.

By accident, a large plate is dropped and breaks into three
pieces. The pieces fly apart parallel to the floor, with
v1 = 2.80 m/s and v2 = 1.75
m/s. As the plate falls, its momentum has only a vertical
component, and no component parallel to the floor. After the
collision, the component of the total momentum parallel to the
floor must remain zero, since the net external force acting on the
plate has no component parallel to the floor....

QUESTION 4 a) The human femur bone breaks if compressive stress greater than 1.50 * 10 N/m2 is imposed on it. Assuming the Young's modulus for bone is 1.50 * 1010 N/m2, determine 1) the maximum force that can be exerted on the femur bone in the leg if it has a cross-sectional area of 4.90 x 10-4 m2 by how much does a 0.400 m long bone shorten if this maximum force is applied compressively to the bone.
