The portable floor crane in the automotive shop is lifting a 320 -Ib engine. For the position shown compute the magnitude of the force supported by the pin at \( C \) and the oil pressure \( p \) against the \( 3.08 \)-in. -diameter piston of the hydraulic-cylinder unit \( A B \). Assume \( a=6 \) in., \( b=32 \) in.., \( c=16 \) in., \( e=46 \) in., and \( \theta=30^{\circ} \). Answers: \( C= \) Ib \( p= \) \( \mathrm{Ib} / \mathrm{in}^{2} \)
