You are analyzing a polymer uniaxial tension member used in a lightweight structure. The bottom of the tension member is fixed and the top has a tensile force F = 10,000 pounds on it.
a) List the inputs necessary to determine the stress in the member immediately after the load is applied
b) List the inputs necessary to determine the axial displacement at the top of the member immediately after the load is applied
c) List the inputs necessary to determine the stress in the member 100 days after the load is applied
d) List the inputs necessary to determine the axial displacement in the member 100 days after the load is applied
e) Assuming you had the necessary inputs to get a numerical value for both C and D, how might your numerical answers for both C and D vary if the polymer tensile member is located in Michigan versus Texas? Why?
A piston-cylinder device contains 0.2kg of water initially at 800 kPa and 0.06m^3. Now 200 kJ of heat is transferred to the water while its pressure is held constant. Determine the final temperature of the water.
Carbon disulfide (CS2) reacts with excess chlorine (Cl2) to produce carbon tetrachloride (CCl4) and disulfur dichloride (S2Cl2). If 69.7 g of CS2 yields 62.6 g of CCl4, what is the percent yield? (Hint, you must first write the balanced equation.)
You wish to retire at age 66 and at the end of each month thereafter for 30 years, to receive $5000. Assume that you begin making monthly payments into an account at age 24.
An equal tangent vertical curve conects an initial grade of -3% and a final grade of +1% and is designed for 60mi/h. The PVI is at station 250+50 and elevation 732 ft. What is the station and elevation of the lowest point on the curve
A solid steel shaft with an outside diameter of 65 mm is subjected to a pure torque of 7,000 N-m. The shear modulus of the steel is G=80 GPa. Determine a. 1 The maximum shear stress in the shaft
Determine largest load P that can be applied without any cable exceeding its yield strength. Bar length in 10 ft with aluminum directly in the center and steel cables 5 feet on either side. Steel cable lengths are 8 ft and aluminum cable is 10 ft...
The stationary disk, of 300 mm radius, is attached to a pin support at D. The disk is held in place by the brake ABC in contact with the disk at C. The hydraulic actuator BE exerts a horizontal 400 N force on the brake at B.
Briefly explain the difference between piezometer and tensiometer with respect to the working principle, special design consideration and limitation of the instrument.
a whirlpool is modeled as the combination of a free and a forced vortex. the maximum velocity in the whirlpool is 10 m/s, and the radius at the juncture of the free and the forced vortex is 10m.
Calculate the area of a piece of property bounded by a traverse and circular arc with the following coordinates at angle points: A (1275.11, 1356.11), B (1000.27,1365.70),C (1000.00, 1000.00),D (1450.00, 1000.00)
What is the settling velocity of a floc of diameter 0.15 mm and density 2.12 g/cm3 in water. Will the floc from problem 4 be completely removed in a typical sedimentation basin if alum was used as the coagulant.
A rectangular beam made using concrete with f'c = 6000 psi and steel with fy=60000 psi has a width b= 20 in. The concrete modulus of rupture fr=530 psi.
