A wheel barrow is used to lift a 200 lb load. The length from the center of the wheel to the center of the load is 2 ft. The length from the wheel to the effort is 5 ft. 1. Illustrate and annotate the lever system described above. 2. What is the ideal mec

1. The lever system described in the problem can be illustrated as follows: Effort / / Load Wheel | | |----2'----| | | The load is located 2 feet away from the center of the wheel, and the effort is applied 5 feet away from the center of the wheel. 2. The ideal mechanical advantage of the system can be calculated by dividing the input distance by the output distance. In this case, the input distance is 5 feet and the output distance is 2 feet. Therefore, the ideal mechanical advantage is: Ideal mechanical advantage = Input distance / Output distance = 5 / 2 = 2.5 3. To calculate the ideal effort force needed to overcome the resistance force in the system, we can use the equation for static equilibrium, which states that the sum of the forces acting on a system must equal zero. In this case, we can write: Effort force x Effort distance = Resistance force x Resistance distance Plugging in the given values, we get: Effort force x 5 = 200 x 2 Solving for the effort force, we get: Effort force = (200 x 2) / 5 = 80 lb Therefore, the ideal effort force needed to lift the 200 lb load using the wheel barrow system described in the problem is 80 lb.
