Answer the following question about the interactive cantilever modeling system. Consider that a rigid bar is connected to a wall via a free rotating joint, and the spring maintains the bar in a horizontal position, as shown below. Ignore the radius of the bar. Specify the resting length of the spring in \( \mathrm{cm} \). Assume that mass of the bar is \( 10 \mathrm{~kg} \) and is uniformly distributed, gravitational acceleration is \( 9.8 \mathrm{~m} / \mathrm{s}^{\wedge} 2 \), and the spring constant is \( 1000 \mathrm{~N} / \mathrm{m} \). Round the answer to the nearest integer, and input the number only.

Step 1
We have a cantilever system where a rigid bar is horizontally balanced by a spring attached to its end and the wall. The goal is to find the resting length of the spring. Show more…

Determine the angle $\theta$ for equilibrium and investigate the stability at this position. The bars each have a mass of $10 \mathrm{kg}$ and the spring has an unstretched length of $100 \mathrm{mm}.$
Determine the maximum distance that a 20 kg mass will fall if it is released from rest above a nested spring system. The outer spring system has a spring constant of 200 N/m while the inner spring constant has a constant of 500 N/m. The 100 mm indicates that the inner spring is engaged only after the outer spring is compressed 100 mm.

The uniform slender bar of mass $m$ pivots freely about a horizontal axis through $O .$ If the bar is released from rest in the horizontal position shown where the spring is unstretched, it is observed to rotate a maximum of $30^{\circ}$ clockwise. The spring constant $k=200 \mathrm{N} / \mathrm{m}$ and the distance $b=200 \mathrm{mm} .$ Determine $(a)$ the mass $m$ of the bar and $(b)$ the angular velocity $\omega$ of the bar when the angular displacement is $15^{\circ}$ clockwise from the release position.
