The free body diagram below represents a 1500 kg car sitting on a 3000 kg uniform bridge supported at its far ends. The car's position is three quarters of the length L from the left end of the bridge. Identify the error in the equation below: (-0.5L) FEarth on bridge - (0.75L) FEarth on car -LF1 + LF2 F₁ = 0 FEarth on bridge F₂ FEarth on car Select one: Oa. F₁ never produces a torque on the bridge no matter where the axis of rotation is placed. Ob. F₂ never produces a torque on the bridge no matter where the axis of rotation is placed. c. Because the perpendicular distance to F₁ from the left end of the bridge is 0, LF, should be 0. d. Because the perpendicular distance to F₂ from the right end of the bridge is 0, LF₂ should be 0. e. Torques have been taken about two axes and summed.

A uniform 100-lb beam is held in a vertical position by a pin at its lower end and a cable at its upper end. A horizontal force (magnitude P) acts as shown in the figure. If P = 75 lb, what is the vertical force at the pin? To get credit, please, upload a picture of your detailed solution (every step) including FBD and reference frame. No credit will be given for solutions with no justification of every step. Select one: Ⓒa. 127 lb Ob. 28 lb O c. 61 lb O d. 47 lb e. 75 lb Of. 69 lb 9. 54 lb Clear my choice 3.00 son
