Practice Questions
Question 1
Which of the following conditions is necessary for a rigid body to be in static equilibrium?
Question 2
A uniform rod of mass $M$ and length $L$ is suspended horizontally by two vertical strings attached at its ends. If the rod is in equilibrium, what is the tension in each string?
Question 3
A uniform beam of mass $m$ and length $L$ is supported by a pivot at its center. A block of mass $2m$ is placed at one end of the beam. To maintain equilibrium, where must a second block of mass $m$ be placed on the other side of the pivot?
Question 4
A particle is subjected to three forces: $F_1 = 5 \text{ N}$ in the positive x-direction, $F_2 = 3 \text{ N}$ in the positive y-direction, and $F_3$ which is unknown. If the particle is in static equilibrium, what is the magnitude of $F_3$?
Question 5
