a round steel alloy bar with a diameter of 0.75 in and a gauge length of 3.0 in was subjected to tension, with the results shown in the accompanying table. using a computer spread sheet program, plot the stress-strain relationship. from the graph, determine the young's modulus of the steel alloy and the deformation corrsponding to a 8225 lb load.
load(lb) Deformation 10^-4 in.
If a hook can sustain a maximum withdrawal force of 250 N inthe vertical direction, determine the maximum tension, T, that can be exerted.
Determine the critical load of a round wooden dowel that is 0.9m long and has a diameter of (a) 10mm (b) 15mm. Use E=12GPa
If the aluminum wing has an I of 745 in^4 and aluminum has an E of 10.1 *10^6 psi, how much would the end of the wing deflect relative to the fuselage of the aircraft compared to the position it has when aircraft is on the ground.
A 2 m diameter semicircular channel made of brickwork is to transport water to a distance of 1.7 km uniformly. If the flow rate is to reach 200 m3/min when the channel is full, determine the minimum elevation difference across the channel.
A temporary diversion has been constructed on a highway of +4 percent gradient due to major repairs that are being undertaken on a bridge. The maximum speed allowed on the diversion is 10 mph
A steel rod to which three disks are attached is shown below. The rod is fixed against rotation at its left end, but free to rotate in a bearing at its right end. Each disk is 300mm in diameter.
A 6ft wide, 10ft high vertical rectangular gate has its top edge 6ft below the water level. it is hinged along its lower edge. what force, acting on the top edge, is necessary to hold the gate shut
A two thousand gallon tank has two influent streams. Influent one has a flow of 20 GPH and a salt concentration of 100 mM; influent two has a glow of 15 GPH and a salt concentration of 200 mM. What is the steady-state concentration of salt in the ..
You borrow $1000 and pay off the loan with interest after 4.5 years. The amount paid is $1500. What is the effective annual interest rate for this loan. Use a 6 month interest period.
Air at 90 psia and 70 degrees F flows through a 4.5 inch diameter welded steel pipe (e = 0.00015) at 60 lb/min. Find the friction head loss and pressure drop in 200 ft of this pipe. Assume the air to be of constant density.
If the force exerted on cable AB by the motor is F =(100^3/2) N, where t is in seconds, determine the 50-kg crates velocity when t = 5s. The coefficents of static and kinetic friction between the crate and the ground are u(s) =.4
