6- In the design of the robot to insert the small cylindrical part into a close-fitting circular hole, the robot arm must exert a 90-N force P on the part parallel to the axis of the hole as shown. Determine the components of the force which the part exerts on the robot along axes (a) parallel and perpendicular to the arm AB, and (b) parallel and perpendicular to the arm BC. Ans.(a) -77.9 N, 45 N; (b) 63.6N ,63.6N 15°, 45° P 90 N 60

2. The resultant of the three cable forces pulling on A is vertical and equal to the weight, W, of the suspended object. All three cables are in ten- sion. (They pull on the ring at A.) If the angles ß and y, as well as the weight W and forces FAB and FAc in cables AB and AC, respectively, are given, what are the force FADİN cable AD and the angle 8 in terms of given quantities? B D. A

For the frame shown, determine: Horizontal Component of the force at B,C,D and Vertical component of the force at B,C,D in lb. Need only a handwritten solution only (not a typed one).
