The engine of a car is being lifted out of the car by using a pulley system. The weight of the engine is 8000N. Use a scale diagram to determine the horizontal force, F1 that a mechanic has to use to hold the engine in such a position that the rope makes an angle of 30degrees with the vertical. Also determine the magnitude of the force, F2 that the rope exerts on the engine. Determine the magnitude of F1 and F2 both graphically and algebraically.
