Q: A 200-lb trap door (AB) is supported by
A 200-lb trap door (AB) is supported by a strut (BC) which is pin connected to the door at B (see figure). (a) Find reactions at supports A and C. (b) Find internal stress resultants N, V, and M on th...
See AnswerQ: A plane frame is constructed by using a pin connection between segments
A plane frame is constructed by using a pin connection between segments ABC and CDE. The frame has pin supports at A and E and joint loads at B and D (see figure). (a) Find reactions at supports A and...
See AnswerQ: A plane frame with pin supports at A and E has a
A plane frame with pin supports at A and E has a cable attached at C, which runs over a frictionless pulley at F (see figure). The cable force is known to be 500 lb. (a) Find reactions at supports A a...
See AnswerQ: A large precast concrete panel for a warehouse is raised using two
A large precast concrete panel for a warehouse is raised using two sets of cables at two lift lines, as shown in the figure part a. Cable 1 has a length L1 = 22 ft, cable 2 has a length L2 = 10 ft, an...
See AnswerQ: A plane frame with a pin support at A and roller supports
A plane frame with a pin support at A and roller supports at C and E has a cable attached at E, which runs over frictionless pulleys at D and B (see figure). The cable force is known to be 400 N. Ther...
See AnswerQ: A 150-lb rigid bar AB, with frictionless rollers at
A 150-lb rigid bar AB, with frictionless rollers at each end, is held in the position shown in the figure by a continuous cable CAD. The cable is pinned at C and D and runs over a pulley at A. (a) Fin...
See AnswerQ: A plane frame has a pin support at A and roller supports
A plane frame has a pin support at A and roller supports at C and E (see figure). Frame segments ABD and CDEF are joined just left of joint D by a pin connection. (a) Find reactions at supports A, C,...
See AnswerQ: A special vehicle brake is clamped at O when the brake force
A special vehicle brake is clamped at O when the brake force 1 P is applied (see figure). Force P1 = 50lb and lies in a plane that is parallel to the x-z plane and is applied at C normal to line BC. F...
See AnswerQ: Space frame ABCD is clamped at A, except it is free
Space frame ABCD is clamped at A, except it is free to translate in the x direction. There is also a roller support at D, which is normal to line CDE. A triangularly distributed force with peak intens...
See AnswerQ: Space frame ABC is clamped at A, except it is free
Space frame ABC is clamped at A, except it is free to rotate at A about the x and y axes. Cables DC and EC support the frame at C. Force Py = 250lb is applied at the mid-span of AB, and a concentrated...
