Beam AB has a square cross section of 100 mm by 100 mm. Bar CD has a diameter of 10 mm. If both members are made of A992 steel, determine the vertical displacement of point B due to the loading of 10 kN.
Compute the magnitudes of the normal stresses (sigma,x) and (sigma,y) in front of a surface crack of length 2.0 mm in response to a nominal tensile stress of 100 MPa at the following positions:
Water flows down a wide and shallow rectangular channel of concrete (n=0.015) laid on a slope of 0.004. find the depth and the rate of flow in SI units for critical conditons in the channel
The hollow circular shaft is subjected to the torque of 4 kN # m. Determine the principal stress developed at a point on the surface of the shaft.
A bicyclist is riding a bicycle on a flat road. The combined mass of the bicyclist and bicycle is = 110kg, the radius of each wheel is = 32.5cm, and the coefficient of rolling resistance between the tires and the road is = 0.245 cm.
The constant of spring AB is k, and the spring is un stretched when θ = 0. Knowing that R = 10 in., a = 20 in., and k = 5 lb/in.,
If the arm is pulled back such that s= 100 mm and released, determine the speed of the 0.41-kg pinball B just before the plunger strikes the stop, i.e., s= 0. Assume all surfaces of contact to be smooth.
A particle with a mass of 0.5 kg has a velocity of 10 m/s in the x-direction at time t = 0. Forces F1 and F2 act on the particle, and their magnitudes change with time according to the graphical force-time history shown.
Consider two alternative water resource projects, A and B. Project A will cost $2,533,000 and will return $1,000,000 at the end of 5 years and $4,000,000 at the end of 10 years.
Explain what you observe, how an engineer can use this information, and detail your findings in a brief paper no longer than 10 pages. You may work in a group of up to 3.
Water flows uniformly in a 6 m wide rectangular channel at a depth of 0.8m. The channel slope is 0.0015 and n=0.014. Find the flow rate in m3/s
A floor slab has a fundamental bending frequency of 10Hz. A shaker is placed at the centre of the slab for a dynamic testing. The tests confirm that the slab displays a damping ratio of 2% of critical.
The soil properties are Cc = 0.4, Cr = 0.1 and fsat = 18 kN/m3 for both clays, and the water table is 1 m below the soil surface. Determine the settlements when a stress of 60 kPa is applied by the building.
