Answer 1

Break the beam in two part from Hinge point B 400 lb - 4in tu Due to symmetry R = By = 400 → Ri = By = 200 lbs 16V by = 200lbs v=42 lbflin so Ri= 200 lbf zinten loin Ety = 0 & Ret Rz = 200 + 42 x 10 – – – – EM 0 200x12-Rx/0+ 42x10x5 =0 R = 450 lbf from equation 0 R3 = 170 Iles / SF x =-1704 42 n =0 na 4.047 in 250lbs = 170 x 4.047 at n = 4:047 - 42 (4.047) 200 lbs 1-170 lbf SFD ?
