A significant obstacle in the design of atomic weapons is theso-called delta phase instability (a type of mixed dislocation) inPu-239. This is the problem: We wish to construct a sphericalatomic bomb core out of pure delta phase (f.c.c.) Pu-239. A deltaphase instability has shear strain θ = er and shearstress T = (sinr)/2πr2 where r is in cm, θ isunit less, and T is in units of N/cm2 . Assume that forthe purposes of elastic energy calculations ro = 0, andthat there is a single instability. The density of Pu-239 is listedas 19.8 gm/cc. Compute the excess elastic energy E associated withthis instability. Be very careful with units and dimensions.

A train starts from rest at station A and accelerates at 0.5m/s^2 for 60s. Afterwards it travels with a constant velocity for 25min. It then decelerates at 1 m/s^2 until it is brought to rest at station B.
The siphon crown is 1.2m above the water surface elevation of the reservoir and a length 10m away from the siphon entrance. If the siphon diameter is 30 cm, if the friction factor is .02, and the headless coefficient are .2 (inlet) and 1 (exit),
7 g helium at 50 kPa and 200 K (ideal gas, M = 4, k = 5/3) are compressed polytropically in a quasistatic process with pv1.8 to 600 kPa. find the final temperature of helium. find the work and heat interactions
Write Darcy's equation in 2-D. There are three piezometers in an unconfined sand aquifer as shown below. The head measurements at A = 104.56 ft, B = 104.53 ft, C = 103.42 ft. The rate of recharge here is estimated to be 1.25 ft/yr.
A 12inx1inx3in ASTM 36 steel bar is loaded with an axial load of 90,000lbs and a transversal load of 288,000lbs (force applied perpendicular to the 1in side) The proportionality limit is 34,000psi.
A finished 2 x 4 timber (actual size 1 5/8 in. x 3 1/2 in. x 10 ft long) is used as a fixed-end, fixed-end column. If the modulus of elasticity for the timber is 1600 ksi and a factor of safety of 3 with respect to failure by buckling is specified
What points along the line of action of the force F_evec would simplify the calculation of M, the magnitude of the total moment due to the force F_evec about point O
determine the magnitude Fs of the tensile spring force in order that the resultant of Fs and F is a vertical force . Determine the magnitude R of this vertical resultant force.
calculate the magnitude and direction of the horizontal force exerted on the contraction (not on the water). Assume that there is no loss of energy in the contraction. Use the gamma of water is equal to 1000 kg/m^3
Consider again the proposed water treatment plant for a city of 100,000 people where the maximum daily water usage rate is 99 X 106 L/d. Determine (a) the number of kilograms of chlorine needed per day and (b) the capacity of the contact tank.
A 1,000 L water tank contains 1,200 moles of an experimental chemical that is a weak acid with pka of 7.2. The PH of the tank is 9.0. what is molar concentration of the chemical that will dissolve in the water at PH 9.0
