A moment M is slowly increased as it is applied to the disk shown in Fig. tential energy of the system with respect to a reference at e = 0° as the disk is rotated to the position 0 = 45°. The spring (k = 10 lb/in.) is unstretched at e = 0°. Determine the change in po- W = 50lb 16 in. M 8 in. www A

For clarity on the process I should use, as well as the solution. So far the formulas im considering is gravitational potential, kinetic.

The frame shown is fitted with three 45 cm diameter frictionless pulleys. A force of F = 575 N is applied to the rope at an angle = 42°. Member ABCD is attached to the wall by a fixed support at A. Find the forces indicated below. Note: The rope is tangent to the pully (D) and not secured at the 3 o'clock position. a. Variable Value 68 cm 45 cm 64 cm 169 cm a b •G с d b Values for dimensions on the figure are given in the following table. Note the figure may not be to scale. * .E N. d XÂN-m. @c030 BY NC SA 2013 Michael Swanbom For all answers, take zas positive to the right and y as positive upward. At point A, the fixed support exerts a force of: = 190 ✓i+ 427 and a reaction couple of: MA 1402 Member CG is in compression 337 N and carries a force of magnitude

A truck of mass 3 tonnes runs into a buffer stop having three buffer springs each of 40 kN/cm stiffness connected in parallel. Find the maximum compression of the springs, and the load if the wagon is travelling at 60 kmph. 1-Equivalent Stiffness of spring in kN/mm is 2-Kinetic Energy in kNmm is 3-The maximum compression of the spring in mm is 4-Load acting on the spring in kN is
