As shown in Figure, a stone is thrown vertically into the air from the top of tower 100 ft. high. At the same instant, a second stone is thrown upward from the ground. The initial velocity of first stone is 50 ft/sec and that of second stone is 75 ft/sec. When and where will the stones be at the same height from the ground? Sa =? Vi,=50 ft/sec Sb = ? 100.0 ft Tower Vip=75 ft/sec

Design of structures using FEA

An arrangement, in which various members are interconnected with their constrained relative motion, the whole arrangement is then known as a structure. The degree of freedom of such a structure is zero. In such a structure, the load can act throughout the length of the structure or at the joints.
