Concept explainers

Rigid Body

A rigid body is an object which does not change its shape or undergo any significant deformation due to an external force or movement. Mathematically speaking, the distance between any two points inside the body doesn't change in any situation.

Rigid Body Dynamics

Rigid bodies are defined as inelastic shapes with negligible deformation, giving them an unchanging center of mass. It is also generally assumed that the mass of a rigid body is uniformly distributed. This property of rigid bodies comes in handy when we deal with concepts like momentum, angular momentum, force and torque. The study of these properties – viz., force, torque, momentum, and angular momentum – of a rigid body, is collectively known as rigid body dynamics (RBD).

Question

The wheels, axle, and handles of a wheelbarrow weigh \( W = 57 \, \text{N} \). The load chamber and its contents weigh \( W_L = 563 \, \text{N} \). The drawing shows these two forces in two different wheelbarrow designs. To support the wheelbarrow in equilibrium, the man's hands apply a force to the handles that is directed vertically upward. Consider a rotational axis at the point where the tire contacts the ground, directed perpendicular to the plane of the paper. Find the magnitude of the man’s force for both designs.

**Diagram Explanation:**

- **Diagram (a):**
- The wheelbarrow shows two forces: the weight of the wheelbarrow components \( W \) and the weight of the load \( W_L \).
- Distances given:
- 0.400 meters from the rotational axis to the point where \( W_L \) acts.
- 0.700 meters from the rotational axis to the point where the force \( F \) is applied.
- 0.200 meters from the point where \( F \) is applied to the point where \( W \) acts.

- **Diagram (b):**
- Similar to diagram (a) with different distances:
- Distances given:
- 0.600 meters from the rotational axis to the point where \( W_L \) acts.
- 0.700 meters from the rotational axis to the point where the force \( F \) is applied.

**Calculate the man's force \( F \) for:**

- \( (a) \, F = \)

- \( (b) \, F = \)
