A load $\mathbf{Q}$ is applied to pulley $C$, which can roll on cable $A C B$. The pulley is held in the position shown by a second cable $C A D$, which passes over pulley $A$ and supports a load $\mathbf{P}$. Knowing that $P=750 \mathrm{~N}$, determine $(a)$ the tension in cable $A C B$, (b) the magnitude of $\operatorname{load} \mathbf{Q}$

It is known that the connecting rod $A B$ exerts on the crank $B C$ it $500-\text{lb}$ force directed down and to the left along the centerline of $A B$. Find the moment of the force ahout $C$.

Knowing that the tension in cable $A B$ is $570 \mathrm{~N}$, determine the moment about each of the coordinate axes of the force exerted on the plate at $B$.

Rod $A B$ is held in place by the cord $A C$. Knowing that $c=840 \mathrm{~mm}$ and that the moment about $B$ of the force exerted by the cord at point $A$ is $756 \mathrm{~N}\cdot\mathrm{m}$, determine the tension in the cord.

A wooden board $A B$, which is used as $4$ temporary prop to support a small roof, exerts at point $A$ of the roof a $57 - \text{lb}$ force directed along $B$. Determine the moment about $C$ of that force.

A $4-\text{ft}$ section of aluminum pipe of cross-sectional area $1.75$ in $^2$ rests on a fixed support at $A$. The $\frac{5}{8}-\text{in.}$-diameter steel $\operatorname{rod} B C$ hangs from a rigid bar that rests on the top of the pipe at $B$. Knowing that the smodulus of elasticity is $29 \times 10^6$ psi for steel and $10.4 \times 10^6$ psi for aluminum, find the deflection of point $C$ when a 15 -kip force is applied at $C$.
