The rod of the fixed hydraulic cylinder is moving to the left with a constant speed vA = 25 mm/s Determine the corresponding velocity of slider B when sA = 425mm. The length of the cord is 1050 mm, and the effects of the radius of the small pulley A may be neglected.
Consider the plane polar coordinate velocity distribution V_r=C/r, V_0=K/r, V_z=0, where C and K are constants (a) determine if the equation of continuity is satisfied (b) by sketching some velocity vector directions
A frictionless piston-cylinder contains 2kg of nitrogen at 100 kPa absolute and 300 deg K. The system is compressed polyprotically at a 1.4 exponent (n) until the nitrogen reaches a final temperature of 360 deg K.
A community has a current population of 15,000. 10 years ago, the population was 12,500 and the community has a declining growth rate with a saturation population of 22,000.
An underground gasoline storage tank has leaked benzene into an unconfined aquifer over a period of several months. The aquifer characteristics are: Ambient temperature=8 oC Hydraulic conductivity = 123 ft/day Hydraulic gradient = 0.00091 ft/ft
A vehicle is traveling on a curved section of a road of radius 2500 feet at a speed of 60 mi/h. The motorist suddenly applies their brakes, causing the automobile to slow down at a constant rate. After 8 seconds the speed has been reduced to 45 mi..
Develop a table that shows: 1) How many gallons of water are contained in the tank if the volume is measured in increments of 1 ft from the bottom to the top. 2) The mass of water at each increment, expressed in lbm.
When 0.3 m^3/s water flows through a 150 mm constriction in a 300 mm horizontal pipeline, the pressure at a point in the pipe is 345 kPa, and the head loss between this point and the constriction is 3 m.
Estimate the theoretical fracture strength of a brittle material ifit is known that fracture occurs by the propagation of anelliptically shaped surface crack of length 0.2 mm(0.007874 in)
Find: LOS and speed within the ramp influence area and the outer freeway lanes (one-ramp is followed by off-ramp)
Consider a wide flange steel beam of size W10x60 subjected to a negative bending moment of 24 kip ft. Calculate the maximum compressive and maximum tensile stresses and indicate where the stress will be tensile and where compressive.
You are paying into a mututal fund that earns 6% compound interest. If you are making an annual contribution of $10000, how much will be in the funds in 20 years What if the fund makes 10% What if it loses 5% per year
A load is to be raised 20 ft by the hoisting system. Assuming Gear A is initially at rest, accelerates uniformly to a speed of 120 rpm , determine (a) the number of revolutions exected by gear A in raising the load. (b) The time required to raise ..
