Problem 5 The hanging bar weighs 4 lbf and is connected to the 2 lbf block with a frictionless pin. The block slides along the horizontal plane with no friction. Determine the force P that will keep the bar hanging at a constant angle of 15 degrees.

In Fig. 12-17, suppose the length $L$ of the uniform bar is $2.75 \mathrm{~m}$ and its weight is $185 \mathrm{~N}$. Also, let the block's weight $W=300 \mathrm{~N}$ and the angle $\theta=30.0^{\circ}$. The wire can withstand a maximum tension of $500 \mathrm{~N}$. (a) What is the maximum possible distance $x$ before the wire breaks? With the block placed at this maximum $x$, what are the (b) horizontal and (c) vertical components of the force on the bar from the hinge at $A ?$
End $A$ of the 6 -kg uniform rod $A B$ rests on the inclined surface, while end $B$ is attached to a collar of negligible mass than slide along the vertical rod shown. When the rod is at rest, a vertical force $P$ is applied at $B,$ causing end $B$ of the rod to start moving upward with an acceleration of $4 \mathrm{m} / \mathrm{s}^{2}$. Knowing that $\theta=35^{\circ},$ determine the force $\mathbf{P}$.

In the figure, suppose the length L of the uniform bar is 2.5 m and its weight is 220 N. Also, let the block's weight W = 350 N and the angle ́̑ = 43°. The wire can withstand a maximum tension of 370 N. (a) What is the maximum possible distance x before the wire breaks?
