Determine for the instant of considerationa)The acceleration of point Sb)The velocity of pointP.( 15 points)2.For the mechanism of figure below, crank OFturns counterclockwise about the axis O. The rigidbent bar EFPis pinned to the slider at Ewhich slides in fixed horizontal guides. Thedimensions123are given as C= 0.14 m, C = 0.05 m, C = 0.085 mand R= 0.055 m. Crank OF is balanced and1Zhas a mass moment of inertia about Oof I = 0.02 kg.cm,while the slider Ehas a mass of 3 2m= 0.1 kg. Link EFP, with center of mass at F, as a mass of m= 0.2 kg, and the mass moment2Zof inertia about F of I= 0.1 kg.cm. At the instant of consideration q= 0.8 rad, s = 0.096 2A kinematic analysis has provided the following information at this instant: q(dot) 14.5 rad/sec,q(double dot) = 28rad /sec, s= 0.41m/sand s= 8.78 m/sec(to left), ..2.Ignoring the effects of the friction and gravity, determine for this instant.a) the D’Alembert force set for the crank OF, the rod EFP, and the slider b) the necessary driving torque Ton the link OFc) the forces at the pin F.(25 points)..2m. .. 2E..
