A closed vertical cylindrical vessel, 1.75 m in diameter and 3.5 m high is 75% full of oil (SG=0.8) and is revolved about its vertical axis with a constant angular speed. The vessel is made up of steel 9mm thick with an allowable tensile stress of 85 MPa and has a small opening at the center of the top of the cover. 8. What is the maximum angular speed that the vessel can be revolved?

7. During impact, particles collide with a very short interaction period. The interparticle impulse during an impact collision includes a deformation impulse as particles undergo some combination of elastic and plastic deformation plus a restitution impulse during which some portion of of the deformation is reversed. The magnitude of the restitution impulse is always greater than that of the deformation impulse. True False

In case of emergency, the gas actuator is used to move a 50-kg block B by exploding a charge C near a pressurized cylinder of negligible mass. As a result of the explosion, the cylinder fractures and the released gas forces the front part of the cylinder, A, to move B forward, giving it a speed of 200 mm/s in 0.4 s. (Figure 1) Figure B Part A If the coefficient of kinetic friction between B and the floor is μ = 0.5, determine the impulse that the actuator imparts to B.

Question 15 of 20 A train has a length of 93.8 m and starts from rest with a constant acceleration at time t = 0 s. At this instant, a car just reaches the end of the train. The car is moving with a constant velocity. At a time t = 16.0s, the car just reaches the front of the train. Ultimately, however, the train pulls ahead of the car, and at time t = 36.0 s, the car is again at the rear of the train. Find the magnitudes of (a) the car's velocity and (b) the train's acceleration. (a) Number i > (b) Number i Units Units UNITS CHOICES: no units, s, m, m/s, m/s^2 L
