The cable that supports the bar has an effective modulus and area of 14GPa and 77mm^2 , respectively. Let the lengths be 600mm and 300mm , and the angle 50 degrees . If the permitted additional elongation of the cable is 0.20mm , determine the maximum allowed distributed force per length q.
A polymer that contains internal flaws 1.5 mm in length fails at a stress of 30 MPa. Determine the plane strain fracture toughness of the polymer. Assume a polymer specimen of "infinite" width.
A beam with a total length of 14m, has a 1000N load on the left end, 4m to the right (from the left end of the beam) there is a rolarr, 2m to the right of the rolar begins a 300 N/m load that goes for 4m, and the last 4m has a tapered load of 300 ..
A flat rectangular metal plate measures 17.63 + and - 0.02 inches by 26.85 + and - 0.04 inches. A circular hole of diameter 11.42 + and - 0.03 inches is cut out of the plate.
The effective angle of friction (phi) was found to be 26 degrees for a normally consolidated soil. If the soil is tested in consolidated drained triaxial test under sigma3 = 60 kPa, what would be the failure deviatoric stress sigma1-sigma3 stress
There are 3 forces acting on the ring. using the non vector approach, determine the resultant force of only the 150 Ib and 100 Ib forces. Also calculate the angle between the resultant force and the positive x axis.
If log KSO, calcite (CaCO3(s)) = -8.61 at 50 oC, would calcite be over- or under- saturated in a hot water heater at 50 oC if the water was in equilibrium with calcite at 25 oC (log KSO = -8.30) when it entered the house
During a 5 hour storm event, the precipitation over a 230-acre area is 1.5niches. There is constant infiltration at a rate of 0.12 inches/hour and the depession storage is 17 acre-ft. Is there any runoff from the area during the storm
A soil sample with a water content of 14.5% and unit weight of 128.2 lb/cu. ft. was dried to a unit weight of 118.8 lb/cu. ft. without changing its void ratio. What is its new water content (in %)?
Two identical pool balls of 57.15 mm diameter may move freely on a pool table. Ball B is at rest and ball A has an initial velocity v=v0i. (a) knowing that b=50 mm and e=0.7, determine the velocity of each ball after impact.
The prototype and model will both be in air, if the prototype has a velocity of 500 ft/s and a diameter of 30 ft, what should the velocity for the model be if the model diameter is 2 ft
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
The truss is to be constructed of members with equal cross-sectional areas and using a material with yield stress 700 MPa. The structure must be designed to support a mass (m) of 3400 kg with a factor of safety of 3.
