2 Rods, 1 Spring
Classical Mechanics
Level
3
Two identical, massive rods are hinged at one end and connected together by a massless ideal spring.
If the system is in static equilibrium, what is the angle \(\theta\) (in degrees)?
\(\)
Details and Assumptions:
- Each rod is \(1 \text{ m}\) long and has a mass of \(1 \text{ kg}.\)
- The spring constant is \(k = 50 \text{ N/m}\), and the spring's unstretched length is \(1 \text{ m}.\)
- The two hinges are \(3 \text{ m}\) apart horizontally.
- The strength of gravity is \(10 \text{ m/s}^2\) in the downward, vertical direction.
