To determine the original length of a slender rod given the normal strain and deformation experienced by the rod due to an applied axial load. rod AB is subjected to the loading of two blocks, each of weight W (and where we neglect the mass of the pulley). The loading creates a normal strain in the rod given by
epsilonz= 0.050z^(1/2)
where z is measured in centimeters. This strain corresponds to the total deformation in the rod given by \Delta_B = 4.70cm .
Determine the initial length of the rod, L, measured before the loading is applied
The diameter of the soil column is 8.0 cm, the length of the soil column is 16.0 cm. The hydraulic head loss across the soil specimen is 6.4 cm. Over a period of 3 min, 350 mL of water is collected at the downstream side of the soil specimen.
water from a reservoir is being supplied to a powerhouse that is located at an elevation 935 ft below that of the reservoir surface. Discharging through a nozzle, the water has a jet velocity of 240 fps and a jet diameter of 6 in.
what is the definition of critical state. explain at which stage a critical state may be approached in a drained triaxial text on a overconsolidated clay using stress path and strain-strain plot.
A concrete mix with a 3-inch slump, w/c ratio of 0.50, and sand with a fineness modulus of 2.4 contains 1700 lb/yd^3 of coarse aggregate. Compute the required weight of coarse aggregate per cubic yard.
Estimate the power needed to overcome the aerodynamic drag of a person who runs at a rate of 100 yds in 10 s in still air. repeat the calculations if the race is run into a 20-mph headwind: a 20-mph tail wind.
A light bar AD is suspended from cableS and supports a 20 kg block at C. The extremities A and D of the bar are in contact with frictionless, vertical walls. Determine the tension in cable BE and the reactions A and D
A water main springs a leak and the geyser is estimated to be 20 feet in height. It is also estimated that about 300 gallons per minute is leaking based on flow into gutter. About how big is the hole in the water pipe
A course has true azimuth of 157 degrees 15 minutes and a length of 325 feet. What is the departure of the course
ferryboat queuing lane holds 40 vehicles. If vehicles are processed (tolls collected) at a uniform deterministic rate of 5 vehicles per minute and processing begins when the lane reaches capacity
CALCULATE THE REQUIRED DIAMETER OF STEEL TIE RODS NECESSARY TO SUPPORT A BALCONY. EACH ROD, SUSPENDED FROM A ROOF TRUSS, SUPPORTS A FLOOR AREA OF 7.0m^2. THE COMBINED BALCONT FLOOR LOAD IS 10.5 kPa
