Question

The weightless strut in the figure below is not attached to the wall; it is prevented from falling only by friction. (Let $w = 385$ N, $L = 4.85$ m and $h = 2.95$ m.) (a) Find the magnitude of the force of friction between the wall and the strut. (b) Find the normal force exerted by the wall on the strut.

Step 1

We can use the given lengths $L$ and $h$ to find this angle. $\sin(\theta) = \frac{h}{L} = \frac{2.95}{4.85}$ $\theta = \arcsin(\frac{2.95}{4.85}) \approx 37.5^\circ$ Show more…
