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. The coefficient of static friction between the disk and the brake = 0.6. What moment must be applied to the stationary disk to cause it to slip in the clockwise direction?
velocity of water in the nozzle is given by V=2t/(1-.5x/L)^2. L = 4ft. When x=.5L and t=3s what is the local acceleration along the centerline. What is the convective acceleration.
At A, the pipe diameter is 24 in and the pressure is 45 psi. At B, the pipe diameter is 12 in and the pressure is 50 psi. Point B is 3 f t lower than A. Find the flow rate if the pump puts 22 hp (16 kW) in to the flow. Neglect head losses.
Describe in your own words the three strengthening mechanisms i.e., grain size reduction, solid solution strengthening, and strain hardening. Be sure to explain how dislocations are involved in each of the strengthening techniques.
What pressure gradient along a streamline, dp/ds, is required to accelerate water upwards in a pipe at 0.5 m/s^2 The incline is 1:10, i.e., 1 m upward for every 10 m horizontal
Property taxes,insurance and storage will run 5%.What is the owning cost for the dozer?Use the time value method to calculate the depreciated portion of the ownership cost.
The program should use both the maximum shearing-strength criterion and the maximum-distortion-energy criterion. It should also print the values of the principal stresses and, if the material does not yield, calculate the factor of safety.
what was involved in the first far-reaching, comprehensive study of Earth's oceans?
Water is pumped 9 mi from a reservoir at elevation 100 ft to a second reservoir at elevation 210 ft. The pipeline connecting the reservoirs has a 54-in diameter. It is concrete and has an absolute roughness of 0.003.
For the FE pin-pin cable model, solve for the deflection and reactions using the partitioned form. What is partitioned form
Determine the Stoichiometric oxygen requirement (pounds of oxygen per pound of fuel) for a fuel containing by weight 50% n-octane,25% 1-heptene and 25% methanol.
A pump is necessary to lift water from the clear well (reservoir) at a water treatment plant to a storage tower 50-ft high and some distance away. A flow rate of 15 cubic per second (cfs) is required (68F).
Based upon the recommended level for CO of 40 mg/m3, the given conditions, AND the fact that the fire will be burning ALL night, should you find another spot to camp b.
