A box that weighs 1600 N is hanging from a crane at the dock. The crane has a square 16 m by 16 m framework as in figure, with four cables, each of t the box. The box hangs 8 m below the level of the framework. Find the magnitude of the force acting on each cable. 400 3 N (-8, -8,0) (-8,8,0) (8,8,0)

Explanation / Answer

Given A(9,0,9) ,B(9,9,0), and C = (0,9,9)

Vector ,mid - point of AB is given by , B - A = { (9-9) i +(9-0) j + (9-9) k} = 9j / 2

C = 9j +9k

hence,w = Cm(AB) = m(AB)- C = 9j/2 -(9j + 9k)= -9j/2 -9k

w = ( 0, -9/2 , -9)
