Determine the smallest distance d to the edge of the plate at which the force p can be applied so that it produces no compressive stresses in the plate at section a-a. the plate has a thickness of 20 mm and p acts along the centerline of this thickness.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
