Step 1
We have a square lamina \(ABCD\) with side length 50 cm, rotating about a hole at \(A\). It is in equilibrium when side \(AB\) is vertical, under the effect of a couple with a moment of \(250 \, \text{gm.wt.cm}\). Show more…

A weightless rod of length $2 l$ carries two equal masses $m$, one tied at lower end $A$ and the other at the middle of the rod at $B$. The rod can rotate in vertical planc about a fixed horizontal axis passing through $C$. The rod is released from rest in horizontal position. The speed of the mass $B$ at the instant rod becomes vertical is (a) $\sqrt{\frac{3 g l}{5}}$ (b) $\sqrt{\frac{4 g l}{5}}$ (c) $\sqrt{\frac{6 g l}{5}}$ (d) $\sqrt{\frac{7 g l}{5}}$

A uniform disk of radius $r=250 \mathrm{mm}$ is attached at $A$ to a 650 -mm rod $A B$ of negligible mass that can rotate freely in a vertical plane about $B$. If the rod is displaced $2^{\circ}$ from the position shown and released, determine the magnitude of the maximum velocity of point $A,$ assuming that the disk is $(a)$ free to rotate in a bearing at $A,$ (b) riveted to the rod at $A .$

A vertical rectangular object of uniform mass M = 12.5 kg has sides a = 0.8 m and b = 3.2 m. It is pivoted from point O as shown in the figure below. If a constant force of F = 91 N along the diagonal as shown is applied, determine the angular acceleration of the rectangle at the instant shown in the figure using SI units. Express your answer with two decimal places. Please use the convention: Clockwise (+), Counterclockwise (-) when expressing your answer. Hint 1: The moment of inertia of the rectangle about an axis of rotation passing through its center of mass is I subscript CM = 1/12 M (a^2 + b^2). Hint 2: Don't forget the force of gravity!!! Take g = 9.80 m/s^2.
