Prob. 1 If the gap between C and the rigid wall at D is
initially I115 mm. determine the support reactions at A and
B when the force P = 200 kN is applied. The assembly
is made of A36 steel.
Equation of Equilibrium: Referring to the freebody diagram of
sin x = cos x
cos x = sin x
tan x = sec2x
cot x = csc2x
sec x = sec xtan
csc x = csc x
cos x dx = sin x + C
sin x dx = cos x + C
