Question
Three rods are welded together to form a "corner" that is supported by three eyebolts. Neglecting friction, determine the reactions at $A,$ $B,$ and $C$ when $P=240 \mathrm{lb}, a=12$ in., $b=8$ in., and $c=10$ in.
Step 1
The six unknowns are $R_{AX}$, $R_{AY}$, $R_{AZ}$, $R_{BX}$, $R_{BY}$, and $R_{CZ}$. The coordinates of points A, B, and C are (12,0,0), (0,8,0), and (0,0,10) respectively. Show more…

The object $A B C$ consists of two slender rods welded together at point $B .$ Rod $A B$ has a weight of $2 \mathrm{lb}$ and bar $B C$ has a weight of 4 lb. Knowing the magnitude of the angular velocity of $A B C$ is 10 rad/s when $\theta=0^{\circ},$ determine the components of the reaction at point $C$ at this location.

The block $A$ and attached rod have a combined mass of $60 \mathrm{kg}$ and are confined to move along the $60^{\circ}$ guide under the action of the 800 -N applied force. The uniform horizontal rod has a mass of $20 \mathrm{kg}$ and is welded to the block at $B$. Friction in the guide is negligible. Compute the bending moment $M$ exerted by the weld on the rod at $B$
Two blocks $A$ and $B$ of masses $10 \mathrm{~kg}$ and $12 \mathrm{~kg}$ respectively are kept on a rough wedge of inclination $30^{\circ}$ and $60^{\circ}$ respectively. The coefficient of friction between the block $A$ and wedge is $0.6$ while that between $B$ and the wedge is $0.3$. The blocks are connected by a light inextensible thread. The wedge is fixed with respect to ground. Tension in the thread connceling $A$ and $B$ is (Take $g=10 \mathrm{~m} / \mathrm{s}^{2}$ ) (a) $24.83 \mathrm{~N}$ (b) $85.92 \mathrm{~N}$ (c) 7.cro (d) $55.79 \mathrm{~N}$
