(a) A mass of 1 kg is to be supported on a spring having a stiffness of 9800N/m. The damping coefficient is 5.9 N-sec/m. Calculate the natural frequency of the system. Determine al
Consider a fully developed laminar flow of a fluid through a 200 m long and 4 cm diameter horizontal and circular pipe. The density and the viscosity of the fluid are 1400 kg/m 3
Q. Can you explain Corners and fillets ? Corners and fillets The intersection of the surfaces in casting must be smooth and forms no sharp angles. For this, the external a
Find out the mechanical advantage of the machines: A lifting machine may lift 800 N by the application of 100 N. Distance moved by the effort is 100 cm. At the same time load
A large hydraulic cylinder is to be treated using autofrettage, taking 80% of the wall thickness into the plastic range. The external diameter of the vessel is 200mm and the inter
Particle in a Box 1 (from Dr. Liebman): You will remember that the energy of a particle in a 3 (and 2) dimensional box is defined by 3 (or 2) quantum numbers. This brings up the co
What are various types of damping ? Explain viscous damping. A vibrating system is defined by the following parameters : m = 4Kg, K = 10N/m, C =3N-Sec/m Evaluate (a) Na
Friction: you have learnt laws of friction and problems involving dry friction. The relative sliding motion of one body on another body is resisted by forces called as frictio
Q. Illustrate Clay content test? Under this test, the clay content is measured by washing it off the sand sample. The standard dried sand sample (50 gm) is put in a mixing devi
The end gear is subjected to the loading given in the picture below. If the bearings A & B exerts only Z & Y component of forces on the shaft, Verify the equilibrium torque T at ge
