Question

Bar ADB is supported by a thrust bearing at A and a vertical wire at B. Knowing that Fis vertical with a magnitude of F = 130 lb and that the section of bar from Dto Bis L - 1.9 ft long, determine the tension in the wire and the reactions at A. Enter the magnitude of the reaction Max below. Express you answer in ft-lb to the nearest whole ft·lb. 6 ft 1.5 ft Your written solution must include an FBD and all calculations necessary to determine the tension in the wire and all reactions at A.

Answer 1

Answer:-

Given That:-

Bar ADB is supported by a trust bearing at A and a vertical wire at B. Knowing that F is vertical with a magnitude of F = 130 lb and that the section of bar from D to B is L = 1.9 ft long. determine the tension in the weire and the reactions at A.

Apply conditions pf static equilibrium.

ΣMy = 0

130 $\times$ 1.5 = T $\times$ (1.5 + 1.9)

Wire Tension, T = 57.342

ΣFx = 0

Ax = 6

ΣFγ = 0

Ay = 0

ΣΕ = 0

A₂ = 130 - T

= 130 - 57.342

A₂ = 72.658 lbs

Enter the magnitude of the reaction M_AX below.

ΣΜ = 0

Max = 130 x 6-T x 6

= 435.948

M_AX = 435.948

M_AY = 0; M_A2 = 0
