a concrete test cylinder is loaded with p= 100k (445 kn) and resulting shortening of 0.036" (0.0914 mm). determine the unit strain developed in the concrete. the hieght of the cylinder is 12" (305 mm) and the diameter is 6" (152 mm).
The owners wish to achieve an initial acceleration from rest of 22 ft/(sec^2) on a level paved surface. What is the minimum coefficient of road adhesion needed to achieve this acceleration
If a torque of T = 1,100 N-m is applied to the composite assembly, determine: (a) the maximum shear stress in the aluminum tube and in the steel core. (b) the rotation angle of end B relative to end A.
Determine the strain components strainx, Strainy, and gammaxy, then sketch the deformed shape in the xy orientation, paying particular attention to the sign of the shear deformation.
Determine the acceleration when t = 4 s, the displacement from t = 0 to t = 10 s, and the distance the particle travels during this time period.
Calculate the vapor pressure, air pressure, relative humidity, and air density at elevation 1500 m if air temperature is 25 degrees C and dew point temperature is 20 degrees C and the lapse rate is 9 degrees C/km
A steady-flow compressor is used to compress helium from 15 psia and 70oF at the inlet to 200 psia and 600oF at the outlet. The outlet area and velocity are 0.01 ft2 and 10 ft/s
calculate the cracking moment (resisting moment) for an unreinforcedconcrete beam that is 10 in. wide, 16 in. high. assume normal weight concrete with 3000 psi = f prime sub c. use the internal couple method and check with the flexure formula.
