## For The Beam And Loading Shown Determine The Reaction At A

The beam is supported by a hinge at A and rollers at C. P -706 is loaded by decreasing triangular load varying from w o from the simple end to zero at the fixed end. 6, compute the moment of area of the M diagrams between the reactions about both the left and the right reaction. The reaction at the roller support, end A, and the vertical reaction at the pin support2, end B, can be evaluated from the equations of equilibrium, Eqns. (Ans: 1302 N, 84. Determine the force P needed to lift the load. a) Determine the reactions at supports A and B. SOLUTION Assume B is positive when directed. 3 Reaction Forces and Moments on Beams with Both Ends Fixed. 12 ft 12 ft 8 ft Beam C Beam D Beam E Beam F. On a transverse cross section 1 ft from the left end, determine a) The flexural stress at point A of the cross section b) The flexural stress at point B of the cross section. Use the following in your calculations: L = 9 ft , po = 10 kips/ ft , P = 40 kips and MD = 90 ft. \(\sum M_{c}\space = 0\) Clockwise moments = Anti clock wise moments. BEAM FIXED AT ONE END, SUPPORTED AT OTHER-CONCENTRATED LOAD AT CENTER. 3, has an initial notch located at d = c · L / 2. The collar is fixed to the rod AB, but is allowed to slide along rod CD. Note that the maximum stress quoted is a positive number, and corresponds to the largest stress magnitude in the beam. = w x length = (50 x 5) = 250 N This will act at the middle 2. Reactions are 1 (2) 2 AD wL a== − From A to B: 0 <
