2. (2p.) A thin horizontal bar of negligible weight and length L is pinned to a vertical wall at A and supported at B by thin wire BC that makes an angle with the horizontal. A weight W can be moved anywhere along the bar as defined by the distance x from the wall. a) Find the tension as a function of x. b) Find the horizontal and vertical components of the force exerted on the bar by the pin at point A. c) If W=315N, L2.76m, and 0-32.0°, find the maximum distance x before the wire breaks if the wire can withstand a maximum tension of 520N.
