[Elastic Properties of Materials] There is a cylindrical bar of copper do in diameter is to be deformed elastically by application of a force along the bar axis. Using the data in Table given below, determine the normal force (F) that will produce an elastic reduction of Ad in the diameter.

Can someone please home me to solve the following question showing all needed work and equation’s. Please and thank you.

Suppose that you used 70 quadratic elements to discretise a bar system (mesh). What is the size of the assembled stiffness matrix? (Hint: if the size of the matrix is 10 by 10, then write 10 in the answer box).

A load P is supported by a structure consisting of rigid bar ABC, two identical solid aluminum alloy [E-73 GPa] rods (1), and a solid bronze [E = 105 GPa] rod (2). The aluminum rods (1) each have a diameter of 12 mm and a length of L₁ - 2.5 m. They are symmetrically positioned relative to middle rod (2) and the applied load P. Bronze rod (2) has a diameter of 22 mm and a length of L₂ - 1.7 m. If all bars are unstressed before the load P is applied, determine the normal stresses in the aluminum and bronze rods after a load of P - 80 KN is applied to the rigid bar.

The elongation of a bar of uniform cross section subjected to an axial force is given by the equation (omega)= PL/AE  What are the dimensions of E if (omega) and L are lengths, P is a force, and A is an area?

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…
