Flexi Says: Look at the wheelbarrow in the Figure here. It is used to carry heavy objects. It consists of two simple machines: a lever and a wheel and axle. Effort is applied to the lever by picking up the handles of the wheelbarrow. The lever, in turn, applies upward force to the load. The force is increased by the lever, making the load

2024525;To balance a car with a mass of 1500 kg, you can use a lever defined by the mechanical advantage: MA = (1500 × g)/(70 × g) = 21.43. where g is the standard gravitational parameter, equal to 9.81 m/s². The arm of the lever on your side should be 21.43 times longer than the arm on the car side.

2024623;To calculate the mechanical advantage of such a system, simply use the following equation: MA = 2 × n. where n is the number of pulleys directly attached to the object. If you were looking for a system of two non-identical wheels connected by a belt loop, you should head straight to our pulley calculator.
