The system is released from rest in the position shown. Calculate the tension T in the cord and the acceleration a of the 30-kg block. The small pulley attached to the block has negligible mass and friction. (Suggestion: First establish the kinematic relationship between the accelerations of the two bodies.)
You will be using a large crane... lets say one with a capacity of 30T. What considerations need to be made prior to picking up a 15T load with the crane? If you are familiar with the use of a crane be sure to include the discussion of the outriggers..
The installation of a radon abatement device is recommended in any home where the mean radon concentration is 4.0 picocuries per liter (pCi/L) or more, because it is thought that longterm exposure to sufficiently high doses of radon can increase t..
Testing has already been completed on the water and the Usage Rate for the carbon is 0.4 pounds of carbon per 1000 gallons of water treated. The required EBCT is 20 minutes and the carbon longevity must be at least 6 months.
The uniform steel shaft has two gears attached to it at B and C, two frictionless bearings, and the motor. The motor generates 15kip·in and the gears consume 10kip·in and 5kip·in. Find the diameter of the shaft if the maximum rotation between A an..
A glass jar is heated in an oven and sealed when the air pressure is 103 kPa and the temperature is 105 C. Find the absolute, gage, and vacuum pressures in the jar when it cools to 20 C.
Given an azimuth of 251 degrees 11' 23" for line ED. If theangle at DEO is 197 degrees 26' 12" measured clockwise, what is theazimuth and bearing of line EO?
A tank containing acetone at 20 oC has a drain pipe connected vertically at the bottom. The pipe is made of galvanized iron, 0.5 in NPS Schedule 40 with length L= 2m. The acetone depth in the tank is H= 5 m.
Compute the design strengths of a rectangular beam with bw=15 in, d = 36 in, d'=2.5 in, fy= 60ksi, fc'=4ksi, and at the top of the beam are 4 #8 bars, the bottom has two rows of 4 #10 beams
Beam AD carries the two 40-lb loads shown. The beam is held by a fixed support at D and by the cable BE that is attached to the counterweight W. Determine the reaction at D when (a) W = 100 lb, (b) W = 90 lb.
A materials engineer is working in a research project to evaluate the effect of one type of admixture on the compressive strength of concrete
Explain the Methods of damp proofing
The steel uniform shaft has four pulleys attached to it and frictionless bearings at its ends. The pulley at B is connected to a motor that is driving the system. The other three pulleys are consuming the power delivered by Pb .
