A person on horseback is on a drawbridge which is at an angle 9 = 20.0° above the horizontal, as shown in the figure. The center of mass of the person-horse system is d = 1.00 m from the end of the bridge. The bridge is = 6.99 m long and has a mass of 1,920 kg. A cable is attached to the bridge 5.00 m from the hinge and to a point on the wall h = 12.0 m above the bridge. The mass of person plus horse is 1,260 kg. Assume the bridge is uniform. Note that the drawing is not to scale and you may not assume that the cable is perpendicular to the bridge. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) (a) Determine the tension in the cable (in N). 20623 X Draw a diagram of the bridge, with forces and distances clearly labeled.

A steel beam, of lengths a = 6 m and b = 3 m and a hollow box cross section, is supported by a hinge support A and roller support B, see Figure Q.1. The width and height of the cross section are 200 mm and 300 mm, respectively, and the wall thickness of the cross section is 5 mm. The beam is under a distributed load of the intensity that linearly varies from q=0 kN/m to q = 3.1 kN/m for AB span; and is constant with q = 3.1 kN/m for BC span. The Young's modulus of steel is 200 GPa. A y, v a 5 mm 200 mm Figure Q.1 9 A B 300 mm b C X
