Question
A linear torsional spring deforms such that an applied couple moment M is related to the spring’s rotation θ in radians by the equation M = (20 θ) N-m.
If such a spring is attached to the end of a pin-connected uniform 10-kg rod, determine the angle θ for equilibrium.
The spring is undeformed when = 0°. Give your answer in degrees and to 3 significant digits.

Transcribed Image Text:The image depicts a physical setup involving a cantilever beam attached to a wheel or pivot at point A. The beam has a length of 0.5 meters and forms an angle θ with the horizontal.
A moment, denoted as \( M \), is applied to the system, which is expressed by the equation \( M = (20 \theta) \, \text{N} \cdot \text{m} \). This equation suggests that the moment is a function of the angle θ, with a proportionality constant of 20 in units of newton-meters per radian.
The diagram illustrates the geometry and forces involved, useful for understanding rotational dynamics and torque in mechanical systems.
