The four forces shown act on the rollers of an in-line skate. Determine the equivalent force-couple system, with the force acting at O (the ankle joint of the skater).
Determine the horizontal component of reaction that the pin A exerts on the two-member frame. Set F = 500 (Find Ax) Determine the vertical component of reaction that the pin A exerts on the two-member frame.
Two long pipes convey water between two reservoirs whose water surfaces are at different elevations. One pipe has a diameter twice that of the other; both pipes have the same length and the same value of f.
The in-situ dry density of a sand is 1.72 Mg/m^3 . The maximum and minimum dry densities, determined by standard laboratory tests, are 1.81 and 1.54 Mg/m^3, respectively. Determine the density index of the sand.
The base engine develops 200 ft-lb of torque, and a modified version of the engine develops 240 ft-lb of torque. If the overall gear reduction ratio is 8 to 1, what is the maximum acceleration from rest (in ft/sec^2) for:
Assume the capacity of a pile supporting a transmission tower is modeled with a log-normal random distribution with a mean of 250 tons and a c.o.v. of 20%.
Water in a piston/cylinder is at 90?C, 100 kPa, and the piston loading is such that pressure is proportional to volume, P ??CV. Heat is now added until the temperature reaches 200?C. Find the final pressure and also the quality if in the two-phase..
Assuming isentropic flow, determine the initial mass flow rate of air through the leak.
The speed of the ball relative to the quarterback is 60 ft/sec. What is the absolute speed of the ball? Treat the problem as two-dimensional.
Water enters a very wide rectangular channel (Manning's n = 0.0149) at a velocity of 12.2 ms-1 and a depth of 0.61 m. An H3 curve forms downstream and the water jumps to a depth of 2.4 m some distance downstream.
CD triaxial compression test the specimen was consolidated under an effective confining stress
The pressure drop across the orifice is 15 kPa, and the coefficient of discharge is 0.62. Determine the mass flow rate in the pipeline.
