ANALYSIS OF STATICALLY DETERMINATE STRUCTURES CE Math solve

SOLUTION
Free-Body Diagram. As shown in Fig. 2–28b, the 60-k force is
resolved into x and y components. Furthermore, the 7-ft dimension line
is not needed since a couple moment is a free vector and can therefore
act anywhere on the beam for the purpose of computing the external
reactions.
Equations of Equilibrium. Applying Eqs. 2–2 in a sequence, using
previously calculated results, we have


+:
©Fx = 0

Ax - 60 cos 60° = 0

Ax = 30.0 k

d+©MA = 0;

-60 sin 60°(10) + 60 cos 60°(1) + By(14) - 50 = 0

By = 38.5 k

+ c©Fy = 0;

-60 sin 60° + 38.5 + Ay = 0

Ay = 13.4 k
