Problem: In both cases the beam has the same mass and length and is attached to the wall by a hinge.1) In which of the static cases shown is the tension in the supporting wire bigger?A) Case 1B) Case 2C) Same

FREE Expert Solution

Torque:

τ=F·d sinθ

Rotational equilibrium:

Στ=0

Take counterclockwise as positive.

Case 1:

mg(L/2) - T1•L•sin 30 = 0
