Consider the rotation of a line segment due to strain. Derive an expression for in terms of the strain components. For simplicity, take dx to lie in the (x1, x2) plane:
Draw diagrams showing that the sign of the rotation you compute for each strain component makes sense physically.
Soil with a unit weight of 19.65 kN/m^3 is loaded on the ground surface by a strip load of 1.5 m wide. The strip load is 365 kN/m of wall length. Determine the vertical stress increment due to the strip load and the total pressure
While cost is an important issue, include some discussion on the potential long-term performance of the selected pavement as compared with other pavements
A clean-earth channel, for which n=0.020, is 6m wide and lies on a slope of 0.005236. Water flows at 30m3/s through the channel and enters a reservoir. The water depth in the channel, just before the entry to reservoir, is 3m.
If a 1.0 m3/s flow water treatment plant uses 10 sedimentation basins with an overflow rate of 15 m3/day.m2, a-what should be the surface area (m2) of each tank?( i got this part right the answer is 567 m2)
Find the present worth of a series of investments that starts at $1000 in year 1 and increases by 12% per year for 20 years. Assume the interest rate is 12% per year.
a 60 -m- long steel wire must not strech more than 48mm when the tension in the wire is 6 kn. determine the corresponding value of the normal stress.
The temperature = 25°C; assume that u = 10^-2 after the addition. Compare the value obtained when ionic strength effects are taken into account with that calculated when it is neglected.
A garage (24 ft x 24 ft x 10 ft) is illuminated by (6) 60 watt incandescent bulbs. It is estimated that 90% of the energy to an incandescent bulb is dissipated as heat. If the bulbs are left on for 3 hours, how much would the temperature in the ga..
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.
It is U) be mounted on a solid steel shaft with a heavy force fit. Specify the dimensions for the shaft and sleeve, and compute the stress in the sleeve after installation. Use the basic hole system.
Using the mean radius of the Earth of 6,371,000 m, reduce the observations to grid and adjust the traverse using the compass rule. Assume that the azimuths given in Problem 10.21 are grid azimuths. Compare this solution with that obtained in Probl..
