d$.$ A bent lever is hinged $($pin supported$)$ at its top and has a force $P$ applied at its bottom as shown. A cable is attached to the lever and runs through a series of pulleys. A weight $W$ hangs from the lower pulley. Assume that the lever, cables, and pulleys are all weightless. Neglect the slight inclination of the cables. If $P=100$ lb $,$ the magnitude of the weight $W$ is most nearly:

$200$ lb $250$ lb $500$ lb $800$ lb $1000$ lb
