Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Please I want answer of that question from these choices
Shown below is a figure of a landing gear configuration on the VS and VD planes (for landing gear the directions V, D, and S are often used instead of x, y and z) This gear unit is assumed to represent one side of the main gear on a tricycle type of the landing gear system. The loading assumed corresponds to a condition of nose wheel up or tail down. The design load on the wheel is vertical and it s magnitude for this problem is 15,000 lbf. Determine the reactions at F, H, and G. The fittings at F and H are pinned and therefore cannot transmit any bending moments. The fitting at G is also a pinned fitting.

a) A line shaft as shown in Figure Q is driven using a motor placed vertically below it. The pulley on the line shaft is 1.6 m in diameter and has belt tensions 7.5 kN and 2.4 kN on the tight side and slack side of the belt respectively. Both tensions may be assumed to be vertical and the weight of the pulley is negligible.
