A free body diagram is a visual representation that depicts all the forces acting on an object without considering the object's shape or orientation. In the case of a cart (1.70 kg) carrying four loads of 20g each, the free body diagram (component view) would include the following:
1. Force due to gravity on the cart (Weight of the cart): The weight of the cart can be calculated using the formula w = mg, where m is the mass of the cart (1.70 kg) and g is the acceleration due to gravity (9.8 m/s²). The weight of the cart would be equal to 1.70 kg × 9.8 m/s².
2. Force due to gravity on each load: Each of the four 20g masses would experience a force due to gravity. The force on each load can be calculated using the formula f = mg, where m is the mass of each load (20 g) and g is the acceleration due to gravity (9.8 m/s²). The force on each load would be equal to 20 g × 9.8 m/s².
3. Force exerted by the ground on the cart (Normal force): Since the cart is resting on the ground, the ground exerts an equal and opposite force on it, known as the normal force. The normal force counterbalances the force due to gravity on the cart and loads and prevents them from falling through the ground.
4. Force applied to the cart (Friction): If the cart is being pushed or pulled, there will be an opposing force called friction acting in the direction opposite to the motion. The force of friction will depend on factors such as the surface on which the cart is placed and the coefficient of friction.
The free body diagram (component view) of the cart and its load would include arrows representing the above forces acting on the cart, with their magnitudes and directions indicated.
describe a free body diagram (component view) of the cart (1.70 kg)and it's load of (four x 20g) masses.
