a 0.3 kg bullet is fired into a 3.6 kg wooden block and becomes embedded in it. knowing that the block and bullet move up the smooth incline for 1.2 seconds before they come to stop. determine the magnitude of the initial velocity of the bullet and the magnitude of the force exerted by the bullet on the block.
A rigid bar of mass m and length L is released from rest in the horizontal position. What is the rod's angular velocity when it has rotated through 90°?
Also determine the axial force and deformation of the diameter due to temperature rise. Let E = 120 GPa and Co-efficient of linear thermal expansion = 0.0000168 per °C.
Consider a thermal energy reservoir at 1500 K that can supply heat at a rate of 150,000 kJ h-1. Determine the exergy of this supplied energy, assuming an environmental temperature of 25 oC.
Important information about Compressive Stress, A circular cross sectional bar with a diameter of 3.25 inches is loaded with a uniform axial compressive load of 22,750 pounds. What is the compressive stress along a cross section of the bar?
