Please help Due in 2 hours. Statics machine equilibrium: reactions- too many unknowns 1. The problem statement, all variables and given/known data The woman using the lat pulldown machine is holding the 80-lb weight stationary in the position shown. What are the reactions at the built-in support E and pin support F? (A and C are pinned connections) 3. The attempt at a solution First, I isolated the pulleys and rope to find the components of the tension at D. Dx=80cos60=40 lb Dy=-40√3 lb Then I set up my three equilibrium equations: ∑ME=0= -(80 lb)(13/6 ft) - (40√3 lb)(17/3 ft) - (40 lb)(27/4 ft) + ME + Fy(25/6 ft) ME= (680√3)/3 +1330/3 + (25/6)Fy ∑Fx= 0 = Ex + Fx + (40 lb) ∑Fy= 0 = Ey + Fy - (80 lb) - (40√3 lb) Right now, I have 3 equations and 5 unknowns, Ex, Ey, ME, Fx, and Fy. I'm probably supposed to break it up into two systems, first just the top portion. But I'm not really sure how to proceed from here. Thank you!
