A geotechnical report has suggested an allowable bearing pressure of 200kPa. Determine the minimum size of the pad footing 2 metres wide for a steel column if a factor of safety of 2.0 is recommended (include an estimate of self weight of the footing in your calculations). The total load of the column is 447.644kN
A closed rigid tank contains 2kg of saturated water vapor initially at temperature of 433K. Heat transfer occurs from the system and the pressure drops to 150kPa. Determine the amount of heat loss by the system.
Design an algorithm that lists all possible rearrangements of the symbols in a string of five distinct characters. (in pseudocode)
a horizontal cylindrical tank 4 ft in diameter and 10 ft long is full of water. find the work done in pumping the water to a point 4 above the top of the tank.
Normal load at failure was 93.8N with a maximum shear load of 38.7N. Find stresses on the failure plane, sketch a graph showing these on the shear stress and normal stress axes. Find the friction angle and shear strength.
Find the change in volume of 16.15 lb of water at ordinary atmospheric pressure for three conditions: Calculate each condition and note the trend.
