A 60.0-cm, uniform, 50.0-N shelf is supported horizontally by two vertical wires attached to the sloping ceiling ($\textbf{Fig. E11.8}$). A very small 25.0-N tool is placed on the shelf midway between the points where the wires are attached to it. Find the tension in each wire. Begin by making a free-body diagram of the shelf.

so we need to find attention in each wire. So let's draw the two diagrams. Ah, this distance right here is 25 centimeters. This distance right here is 20 centimeters and then this distance right here is 75 centimeters. So we can say that. Let's actually let's draw the second diagram T's of one here, 25 noon Force here, 50 noon Force here and T's up to here so we know that this length is 20 centimeters. This is 10 centimeters. This is 10 centimeters, and then this extends further. This is 20 centimeters, so not trying to scale. But we just need the measurements. And so we can say that the sum of forces in the white direction equals T's of one plus t's up to minus 75 noons this equal zero so we can say that teeth of one equal 75 minus tisa, too. We can solve for T's up to and say that the sum of torque some of the torques it's going to be equal. Teo 25 Newtons, times 20 centimeters plus 50 Nunes time. 30 centimeters minus T's up to times 40 centimeters and we find this is the end of equal to zero because this the system has rotational equilibrium. So t's up to is going to be equal to 25 times 20 plus 50 times 30 divided by 40 and so t's up to is going to be able to 50. Nunes. We know that piece of one is 75 minus t's up to. So this would be 75 minus 50 and this is equal in 25 mutants. So this would be teeth of one and teeth, too. That is the end of the solution. Thank you for watching.
