Question

As shown in the figure, a beam is supported by two pillars separated by a distance ℓ = 7.2 m. The beam has a mass M = 95.0 kg, a length L = 16.0 m, and a girl of mass m = 63.0 kg is walking from the left end toward the right.

(a) Calculate the normal force exerted on the beam by the pillar on the right, when the beam is on the verge of tipping.

(b) Calculate the girl's position, when the beam is on the verge of tipping.
m

The image depicts a physics scenario involving a beam, a person, and two supports. Here's a detailed explanation:

1. **Beam and Supports**:
- A beam is placed horizontally on two supports.
- The distance between the supports is labeled \( \ell \).

2. **Person on the Beam**:
- A person with mass \( m \) is walking on the beam.
- The distance from the left end of the beam to the person is labeled \( x \).

3. **Beam's Measurements**:
- The total length of the beam is labeled \( L \).
- The beam has a uniform mass distribution with a total mass \( M \).

This setup is commonly used to illustrate problems in static equilibrium and center of mass in physics. The diagram is useful for solving equations involving torques and forces acting on the beam.
