Question

2. A 10.0 kg, 1 m-long beam rests on two posts and supports a 7.00 kg object as shown in the illustration at right: [3+3+4pt] a. Write down in detail the conditions for static equilibrium of this system: two equations that guarantee no translational motion, and one that guarantees that no rotation takes place; denote/label the chosen pivot on the diagram: force, ?: force, ?: torque, ?: [10pt] b. Compute the weight that the post A must be able to support. [10pt] c. Compute the weight that the post B must be able to support. 100 cm 30 cm $R_{A,y}$ $R_{B,y}$ 75 cm A B

Step 1

- Beam: mass m_b = 10.0 kg, length L = 1.00 m. Its weight W_b = m_b g acts at the beam's center (x_b = 0.50 m from the left end/support A). - Object: mass m_o = 7.00 kg, weight W_o = m_o g acts at x_o = 0.30 m from the left end/support A (as shown). - Supports: Show more…
