1.The uniform 30 kg bar OB is secured to the accelerating frame in the 30 degree position from the horizontal by the hinge at O and roller at A. if the horizontal acceleration of the frame is a equals 20 m/s^2 compute the force Fa on the roller and the x- and y-components of the force supported by the pin at O.
2.Three point loads 10,000, 7500 and 9000 kN act in line 5m apart near the surface of a soil mass. Calculate the vertical stress at a depth of 4m vertically below the centre (7500kN) load.
How many particles would be present in a cubic meter of aerosol at the concentration of the U.S. PM-10 standard or 50 micrograms/cubic meter if the particles are .1 micrometer in diameter.
Structural Analysis 8th edition 4-40 draw the shear and moment diagrams for each member of the frame. Assume A is a rocker, and D is pinned.
water with a static pressure of 1.96knm2 flows through an 800 mm diameter pipe. a pitot tube pressure gage in this pipe
Steam expands in an turbine operating in steady-state conditions with a mass flow rate of 40,000 kg/hr. The steam enters the turbine at 8MPa and 500 C, and exits as a saturated vapor at 40 kPa. If the power generated by the turbine is 8.2 MW, what is..
The rotor of an electric generator is rotating at 200 when the motor is turned off. Due to frictional effects, the angular acceleration of the rotor after the motor is turned off is α=-0.01ω rad/s^2 , where is the angular velocity in rad/s.
The strain in member AB was measured to be 8.9*10-4. If the member is an L3*2 1/2* 1/4 of A36 steel determine the following: a) What is the change in length in inches b) What is the force in the member
Knowing that at t= 3s slider block C has moved 57 mm to the right, Determine the velocity of slider block C at t=0, (b) the acceleration of A and C, (c) the change in position of block A after 5s.
For a ternary system, three components are present; temperature is also a variable. What is the maximum number of phases that may be present for a ternary system, assuming that pressure is held constant?
in a steady process steam is expanded adiabatically in a reversible turbine and then sent to an isobaric heat exchanger
