Question 1 ( 1 0 m a r k s ) A rod of length L = 0.20 m is connected to a horizontal spring at its lower end B and leans against a vertical wall (wall in y-direction) with its upper end A as shown in Figure Q1. The weight of the construction is neglected. If the external force is P = 0, the angle between the rod and the horizontal axis x is α = 45 ° , and the force in the spring at B is F s = 0 (un- stretched). The difference in the y-coordinate between A and B is h. If the force P in vertical direction (in negative y-direction) is increased, point A slides downwards (in negative y-direction) on the surface of the wall (displacement δ A ), and point B moves to the right (in x-direction) compressing the spring (displacement δ B ). (a) Which force P is required to hold point A in a position 0.12 m above point C ? That is, the difference in the y-coordinate between A and B is then h δ A = 0.12 m. (b) When pushing down point A towards point C, the angle α changes from α = 45 ° to α = 0 ° , and the force P changes its magnitude during this process. Find the function P(
