The jack shown below is comprised of 5 members and a spring (AB, BD, CDE, GHJ, EJ, and spring HL) and is subjected to a uniform distributed load of 4000 lb/ft. The spring constant k = 20 lb/in and is stretched a distance of 3 inches when the jack reaches equilibrium. Members CDE and GHJ are parallel, and the force P is applied perpendicular to the end of the L-shaped member ABВ.

A) What is the force P required for the jack to maintain equilibrium?
B) If no pin (total of nine) within the jack assembly can withstand a force of 2000 lb, will the jack be able to support the loading shown? You must justify your answer with calculations.
