【已刪除】1. One of the two forces that constitute a couple is
lb, having a line of action that passes through the point A at (0, 6, 5) ft. The other force has a line of action that passes through point B at (-4, 0, 2) ft. Find the moment of the couple, and the distance between the lines of action of the forces. (25%)
【已刪除】2. Determine the moments of inertia Ix and Iy of the area shown in Figure 2 with respect to centroidal axes respectively parallel and perpendicular to side AB. (25%)
【已刪除】3. A 1.5-lb ball A is moving with a velocity of magnitude 18 ft/s when it is hit by a 2.5-lb ball B which has a velocity of magnitude 12 ft Is as shown in Figure 3. Knowing that the coefficient of restitution is 0.8 and assuming no friction, determine the velocity of each ball after impact. (25%)
【已刪除】4. The two pin-connected bars each have a weight of 10 lb I ft as shown in Figure 4. If a moment of M=60 Ib-ft is applied to bar AB, determine the initial vertical reaction at C and the horizontal and vertical components of reaction at B. Neglected the size of the roller at C. The bars are initially at rest. (25%)
