Question

6P In the connecting rod and crank assembly shown, the connecting rod AB converts the inclined linear motion of roller B to circular motion of A about the fixed point O. At the instant shown, it is known that roller B is moving up the incline at a speed of 6.1 m/s which is increasing at the rate of 2.2 40 m/s/s. (a) Determine the velocity vector at B, vbx vby in m/s and (b) determine the velocity vector at A, vay in m/s. Assume the length of rod AB is 1.9 m, the radial offset OA is 1 m and the angles eta and theta are 75 degrees and 70 degrees spectively.

Answer 1

"In the connecting rod and Grant assembly shown that connecting and A_B convert the Included since motion of adder B. V_H = [V_HZ V^Hy_0] V_HA = [T_HA Y_HA 0] W.H.A = [0 0 w_HA] a_ccH = [acc HZ acc Hy 0] V_A = V_H (w_H_A times T_HA) rightarrow
