(b) gives (c) Let be the tension in the segment of cable between the pulley and the bucket and let be the tension in the seg- ment of cable between the pulley and the cylinder. for the bucket gives and for the pulley gives and Or, for the cylinder gives and which checks. Reflect: The acceleration of the bucket is less than g because the weight of the bucket must accelerate not only the bucket but also the pulley and the cylinder. 10.76. Set Up: The weight of the beam acts 4.0 m from each end. Take the pivot at the hinge and let counterclockwise torques be positive. Represent the force exerted by the hinge by its horizontal and vertical components, and Solve: (a) The free-body diagram for the beam is given in Figure 10.76a. Figure 10.76 (b) The moment arm for T is sketched in Figure 10.76b and is equal to gives (c) gives and gives and This is the force the hinge exerts on the beam.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
