The coefficient of restitution is 0.9 between the two 60-mm-diameter billiard balls A and B. Ball A is moving in the direction shown with a velocity of 1 m/s when it strikes ball B, which is at rest. Knowing that after impact B is moving in the x direction; determine (a) the angle ? ,(b) the velocity of B after impact.
The 160-N weights of the arms AB and BC of the robotic manipulator act at their midpoints. Determine the sum of the moments of the three weights about A.
Get information about a car engine .drive the ideal performance using the appropriate cycle and compare to the actual performance.
A large stationary Brayton cycle gas-turbine power plant delivers a power output of 100MW to an electric generator. The minimum temperature in the cycle is 300K
A circular shaft is subjected to a torque Ta and a bending moment Ma. Assuming that the diameter of the shaft is d, determine the expressions for the principal stresses and maximum shear stress in terms of Ma, Ta and d.
To Verify the law for parallelogram of forces, law for triangle of forces and law of polygon of forces. These laws are very useful to calculate unknown forces in very short time.
In flows past solid bodies, the force exerted on the body by the fluid motion depends upon the fluid velocity u, the density p, the viscosity
