A rectangular beam of size 40mm*60mm is subjected to bending. the maximum bending stress is limited to 75N/mm^2. find the moment of resistance of beam section.
if the atmospheric pressure is 1.025 bar at a location where you can dive in a lake to 30ft below the surface and then
Consider a 210 MW steam power plant that operates on a simple ideal Rankine cycle. Steam enters the turbine at 10 MPa and 500o C and is cooled in the condenser to a pressure of 10 kPa. Show the cycle on a T-s diagram with respect to the saturation li..
a sample of wet silty clay soil has a mass of 126 kg. the following data were obtained from laboratory tests on the
Air with a mass flow rate of 1.5 kg/sec and temperature of 400 K flows through a horizontal duct of an air heater. If 36 kJ/sec of heat is added to the flow, determine the air exit temperature. Assume ideal gas and neglect any change in pressure and ..
The car travels at a constant speed of 25 m/s makes a turn on a semi-circular curve. If it takes 20s to make the semi-circular turn, determine the magnitude of the car’s acceleration during the turn.
steam is contained in a rigid container at an initial pressure of 100 psia and 600 f. the pressure is reduced to 10
A car accelerates from rest along a straight section of road. It starts at position s = 150 m and reaches a speed of 20 m/s at position s = 200 m. It is proposed that this acceleration, a, can be modelled as being a function of position, s, in the fo..
an escalator brings four people of total 300 kg 25 m up in a building. explain what happens with respect to energy
Niobium has the BCC structure with a density of 8.57 g/cm^3 , an atomic weight of 92.91 g/mol. One atom is associated with each lattice point. Calculate the lattice parameter; and the atomic radius of Niobium.
Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 23kW of shaft power. The free surface of the upper reservoir is 46m higher than that of the lower reservoir. If the flow rater of water is measured to be 0.03m^3/s d..
Determining initial acceleration of a projectile How can I proceed to solve the problem below?
The lamp has a mass of 15 kg and is supported by a pole AO and cables AB and AC. If the force in the pole acts along its axis, determine the forces in AO, AB, and AC for equilibrium.
