1.two parallel disks of diameter D are brought together, each with a normal speed of V. when their spacing is h, what is the radial component of convective acceleration at the section just inside the edge of the disk (section A) in terms of D, V, and h. assume uniform velocity distribution across the section.
2.To apply shock loading to an artillery shell, a 20-kg pendulum A is released from a known hight and strikes impactor B at a known velocity Vo. inpactor B then strikes the 1-kg artillery shell C. knowing the coefficient of restitution between all object is e, determine the mass of B to maximize the impulse applied to the artillery shell C.
3.two structural members A and B are bolted to a bracket. knowing that both members are in compression and that the force is 15 KN in member A and 10 KN in member B, determineby trigonmetry the magnitude and direction of the resultant of the force applied to the bracket by member A and B.
