Answer to relevant QuestionsFor the beam and loading shown, determine (a) The magnitude and location of the resultant of the distributed load, (b) The reactions at the beam supports.Determine the reactions at the beam supports for the given loading.A grade beam AB supports three concentrated loads and rests on soil and the top of a large rock. The soil exerts an upward distributed load, and the rock exerts a concentrated load RR as shown. Knowing that P = 4 kN and wB = ...The square gate AB is held in the position shown by hinges along its top edge A and by a shear pin at B. For a depth of water d = 3.5 m, determine the force exerted on the gate by the shear pin.Problem 5.94: For the machine element shown, determine the x coordinate of the center of gravity.Problem 5.95: For the machine element shown, determine the y coordinate of the center of gravity.
