Question

Ax and Ay are incorrect but the value for By is correct. Need help on finding values for Ax and Ay.

Please use the following link as a guide (Exact problem with different values): https://www.chegg.com/homework-help/Engineering-Mechanics-Statics-2nd-edition-chapter-7-problem-93P-solution-9780073380292

Ch. Ex. 93 Determine the support reactions for the loading shown. 1 out of 10 attem Do not round intermediate calculations, however for display purposes report intermediate steps rounded to four significant figures. Give your final answer(s) to three significant figures. Enter tension forces values as positive numbers and compression forces values as negative numbers Determine the support reactions for the loading shown. 13 kN 4.1 kN/m 0.5 kN/m 6.3 m 6.3 m kN, and B kN kN, A

Explanation / Answer

We take moments at point A and equal it to zero as the support is pinned and it cann't take moments,

Moment at A, ------> Triangular portion + point load = udl + support reaction

(0.5 * 6.3 * 4.1 * 2.1) + (13 * 6.3) = (6.3 *0.5 *9.45) + (By * 12.6)

Solving for By -------------------> By = 6.29 kN

Now the total forces in upward direction and downward direction should be equal

triangular portion + point load = reaction at A + UDL + reaction at B

(0.5 *6.3 *4.1) + (13) = Ay + (6.3 * 0.5) + By

25.915 = Ay + 9.44

Ay = 16.475 kN

Ax = 0 as there is no horizontal forces acting on the structure.
