Cart A weighing 120 lbs has a hanging mass B weighing 45 lbs attached to it by a 7 ft cable. The cart is free to slide along the frictionless track. If the system starts at rest with 0 = 45°, find: (a) The velocity of the cart at the moment when the mass is directly underneath it. (b) The velocity of the mass at this same moment.

Please show all work thanks

Given a 2m-length rod with 23.0 mm diameter  what is the actual stress (in MPa) if axial load is 10.4 kN.

Need help on all questions. Please include all units, steps to the problem and information such as its direction or if it is in compression or tension. Thx.

I understand there may be more than questions here, if there is a way of me given more credits but having all answers in one then please advice me. I have inserted a picture with the questions and am struggling with these types of questions, if you could help please

Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me answer all the questions below? Especially the one about the bending moment and shear force. The Figure 2 attached is a simplified structure to undertake a structural analysis on a concept design for a low cost stroller/buggy for children. The buggy consists of a number of metal sections that are pin-jointed together. The buggy is designed to accommodate a child of mass no more than 20 kg, sat on the seat which is supported at four points (Fc) on the frame of the buggy.  Assume that the weight of the child is equally distributed across all of the points  indicated on Figure 2 as Fc. Assume that there are no additional forces applied to the handle of the buggy, that the buggy is static (stationary) and that the buggy, and the elements of the frame have no mass. At points A and G, there are roll supports. At Points B, F and D there are the pin supports. I am required…
