For the following questions answer them individually
Two cantilever beams,‘A’ carrying pointed load of ‘W' at free end and the other 'B' carrying uniformly distributed load totaling to ‘W'. The ratio of maximum deflection of beam A to that of beam B is
A force F is used to pull a 50 kg block, as shown in Figure. Determine the magnitude and direction of the friction force when F = 400 N
When a beam is subjected to bending moment alone, the bending stress at any point from the neutral axis
A fabric filter is to be constructed using bags that are 0.1 m in diameter and 5.0 m long. The bag house is to receive $$5 m^3/s$$ of air. Filtering velocity is 2.0 m/min. Determine the minimum number of bags required for a continuous removal of particulate matter
A load of 20 kg is supported as shown in fig. Assuming the pulley to be ideal and the equilibrium configuration as shownin Figure, determine the tension in cable CD
A pump having an efficiency of 68% delivers 3 L/s of water against a head of 22 m. Compute the power requirementof the pump in W
A heat engine is supplied heat at the rate of 1700 kJ/min and gives an output of 9 kW. The thermal efficiency will be around.
A Carnot cycle which operates between the temperatures of 400K and 300K. If 20000 kcal/hr of heat is supplied, the work output will be
A solid shaft of diameter ‘D’ carries a twisting moment that develops maximum shear stress $$\tau$$. If this shaft is replaced by a hollow one of outside diameter D and inside diameter D/2, then the maximum shear stress will be
