A grain silo is in equilibrium under the effect of a variable distributed wheat load and several forces as shown in the Figure. The silo has a gate for releasing the wheat into a rigid u-shape channel at G for dispensing the crop. The channel is connected to the silo by the hinge (or pin) at G and supported externally by the hinge (or pin) H. The silo is also supported by two rigid links (or pendulums) AB and LN. The acting loads are represented by three concentric forces F = 30 kN at K, F2 = 90 kN at D, and F = 40 kN at J, and a couple M = 300 kNm (clockwise) at C. The distributed load effect of the wheat is vertical acting between points C and G of the silo. The distributed load has a magnitude equal to wi = 250 kN/m between points C and E and decreases linearly to w2 = 80 kN/m when it reaches point G due to the releasing effect of the gate. The angles of forces F2 and F, with the horizontal line are 40° and 20°, respectively. F is horizontal. Do the following: 1. Draw the Free Body…
