Determine the normal force under each tire when the car is in equilibrium. State any assumptions. -1264 mm-863 mm Answers: Normal force under each of the front tires: N₁= N Normal force under each of the rear tires: N₁ = N i iarrow_forward
- Find the center of mass.arrow_forwardThe figure shows the side view of a portable traffic signal. The upper portion of the signal with attached frame has a mass of 90 kg with mass center at G. The signal and frame are hinged at point E and rest on a vertical post at H. In operation, member DEH is positioned vertically by means of the hand-operated winch so that the lights are directed to the left. Determine the necessary input force F that will just start to rotate the signal from its horizontal position. Note that handle A is rigidly attached to gear B.
