Determine the force P required to break contact at C. The body is in a vertical plane, so the weight does have an influence. What is the moment of the weight of the body about point O?arrow_forwardDetermine the n- and t-components of the force F which is exerted by the rod AB on the crank OA. Evaluate your general expression for F = 118 N and (a) e = 30°, B = 25° and (b) e = 21°, B = 29° Answers: (a) Fn= i N, F: = i N (b) Fn = i N. F:= Narrow_forward

When the smooth cam C is in the position shown, determine the force acting on pin B along Y axis and input its absolute value. (If your answer is negative, input its positive value such as -17 --> 17) Use the followings; FA=57N FC=246N K=51mm M=12mm L=22mm O=35degreesarrow_forwardDetermine the magnitude of the moment of P about the z-axis in Nm.arrow_forward
- One of the ends of the rigid rod AB of mass m and length L = 4R is attached to the edge of the radius R disc by a pin. The other end of the rod can slide freely on the ground without friction. A motor connected to the center of the disk at point O rotates the disk at a constant angular velocity D. Find all the forces acting on the rod at the moment θ = 30 degrees and the direction OB is vertical at the moment shown in the figure.arrow_forwardStaticsarrow_forward4/71 The automobile bumper jack is designed to support a 4000-N downward load.
