The beam with hollow box cross-section is supported with a pin at A and a roller at B, where the pin diameter is 1.25 in. The outer dimensions of the box beam are 6 in. high by 8 in. wide and the wall thickness is 0.625 in. The load F0 = 3000 lb. Determine
(a) the bearing stress between the pin at A and the box beam and
(b) the shear stress in the pin at A.
The total dissolved inorganic carbon (TIC) of a sample of groundwater is 8.33 mM. The temperature of the aquifer is 15C, the pH is 7.5, and the ionic strength is 0.05 M. What is the H2CO3, HCO3-, CO3 2-, and the partial pressure of CO2? [Use activ..
The station of a PI of a horizental curve is 60+20. The horizental curve has a degree of 4 and a length of 400ft. the othere given design perameters include. Superelevation runoff rate is 1/400. width of the pavement is is 15ft.
estimate the velocity with which you would contact the ground if you jumped from an airplane at an altitude of 500ft and a) air resistance is negligible, b) air resistance is important, but you forgot your parachute
Assume that the upstream pressure is 60 psi and that the flow is isothermal at 68F, determine the maximum possible mass flow rate of air for which the assumption of incompressible flow is a vaild engineering approximation.
Assuming a density of 120 lb/ft*3 for masonry brickwork,determine the maximum height of a brick wall if the allowable compressive stress is limited to 150 psi,and the brick is (a) four inches wide and (b) six inches wide.
After a long walk in the 8°C outdoors, a person wearing glasses enters a room at 25°C and 40 percent relative humidity.
Car traveling along a circular curve that has a radius of 50m. if its speed is 16m/s and is increasing uniformly at 8 m/s^2 determine the magnitude of its acceleration at this instant.
The water table is at a depth of 1 m. Compute the effective normal stress and the shear stress acting on a plane rotated 60 degrees clockwise from the horizontal at a depth of 2.5 m in this deposit.
Determine the maximum temperature in the tank. Take the thermal conductivity of the wastes as 2.0 W/mK.
