A rocket motor is used to accelerate a kinetic energy weapon to a speed of 3500 mph in horizontal flight. The exit stream leaves the nozzle axially and at atmospheric pressure with a speed of 6000 mph relative to the rocket. The rocker motor ignites upon release of the weapon from an aircraft flying horizontally at U0=600 mph. Neglecting air resistance, obtain an algebraic expression for the speed reached by the weapon in level flight. Determine the minimum fraction of the initial mass of the weapon that must be fuel to accomplish the desired acceleration.
in a pharmaceutical plant a copper pipe kc 400 wm.k with inner diameter of 20 mm and wall thickness of 2.5 mm is used
block c starts from rest and moves downward with a constant acceleration. knowing that after 5 s the velocity of block a relative to block d is 8 ft/s, determine a) the acceleration of the block c. b) the acceleration of portion e of the cable.
Describe on your own words the three strengthen mechanism for metals (i.e. grain size reduction, solid solution strengthening and strain hardening). Be sure to explain how dislocations are involved in each of the strengthening techniques.
Plot the lift and drag forces exerted on an airfoil as a function of velocity. Use velocity values going from 0 to 45 m/s on a log-linear plot (log-scale on the y axis).
Assume they test null hypothesis H0: versus H1: Will the engineers decide to use the steel if H0 is rejected? Will the engineers decide to use the steel if H0 is not rejected?
