Hi, I have been given this pin-jointed frame analysis to solve (see pictures of the structure attached). Can you help me? 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 to determine the following: 1) Draw a free-body diagram of the structure 2) Simplify the Free…

Figure 2.1 shows an apparatus used to rehabilitate the elbow for a variety of medical conditions. The apparatus consists of a cylindrical bar with a track in which a slider can move. The bar is strapped and fixed on the patient's body while the hand is strapped on the slider.

A alank of wood is fixed to a wall using a hinge. When the angle between the plank and the wall is 45°, a spring is attached to the wood 25cm from the hinge and fixed to the wall so that it is horizontal (Diagram A). The wood is then pushed downwards until it is perpendicular to the wall (Diagram B). The force exerted by the spring, depends on its length. As the spring stretches, the force it exerts increases. A graph showing this relationship is below. 70 Diagram B 60 Diagram A spring 50 90° 20 25cm 45 90° 10 25cm hinge 10 35 15 20 25 30 Spring Length (cm) (a) Calculate the length of the spring in Diagrams A and B.
