Answer to Question #314894 in Mechanical Engineering for luke.

Question

The link lengths for the four-bar linkage are given in the figure. In the

position shown, coupler link 2 is subjected to force F₂ of magnitude

47 N at an angle of 132⁰, and follower link 3 is subjected to force F₃

of magnitude 30 N at an angle of 128⁰. Determine the shaft torque T₁

on input link I and the bearing loads for static equilibrium.

GIVEN:

l₁=30mm; l₂=100mm; l₃=50mm.

$\phi1 = 135 degree , \phi2=17 degree, \phi3=85 degree .$

r₁=0, r₂=45mm, r₃=38mm.

O₁O₃ = 70mm, O₁B=30mm, BC=100mm, O₃B=50mm.

(Answer ASAP. I wish I could attach the figure!)
