Q1: The 800 N tension force in cable AB is required to prevent the CA bar from rotating clockwise. Resolve this force in to two perpendicular components, along X and Y axes. C 70 2.5 m

A force F of magnitude 940 lb is applied to point C of the bar AB as shown. Determine both the x-y and the n-t components of F. F = 940 lb 31' 54° B Answers: Fx= Fy= Fn= Ft= i i i lb lb lb lb

Compression member AB is used to hold up the 325 x 500-mm rectangular plate. If the compressive force in the member is 320 N for the position shown, determine the magnitude of the projection of this force (as it acts at point A) along diagonal OC. Express your answer in units of N. Report the projection as a positive number. 325 30° O 410 320 180 C B 100
