The van seen from the rear is traveling at a speed v around a turn of mean radius r banked inward at an angle θ. The effective coefficient of friction between the tires and the road is μ Determine (a) the proper bank angle for a given v to eliminate any tendency to slip or tip, and (b) the maximum speed v before the van tips or slips for a given . Note that the forces and the acceleration lie in the plane of the figure so that the problem may be treated as one of plane motion even though the velocity is normal to this plane.
A person with a mass of 200kg wearing snow skis is gliding down a long slope at an angle of 20 degrees. Each ski is 200cm long and 5 cm wide. The pressure of the skis on the snow melts a thin layer of water so that a .1mm layer of water exists under ..
The ramp shown below is used to assist passengers boarding light commuter aircrafts. The average mass of the ramp and passengers is 800 kg with the center of mass located at point G. As the ramp angle θ increases, the hydraulic cylinder extends bu..
A hydraulic jump is observed to occur in a channel with a mild slope at a flow rate of 20cfs/ft. If the depth before the jump is 1 ft, determine the depth after the jump.
A vertical curve of 600 ft in length is used to connect two tangents with the following locations: Tangent 1.- Point 1, Sta = 59+00, El = 1250.0' Point 2, Sta = 72+00, El = 1190.0' Tangent 2.- Point 1, Sta = 72+00, El = 1190.0' Point 2, Sta = 84+0..
What are the three meterials based on the predominant types of bond and what are the predominant types of bond in each category?
The small sphere of mass (m) is suspended initially at rest by the two wires. If one wire is suddenly cut, determine the ratio (k) of the tension in the remaining wire immediately after the other wire is cut to the initial equilibrium tension.
The power loss, p , in a journal bearing depends on length, L; diameter, D; clearance, c; and rotational speed, w. You also have to worry about lubricant viscosity, density, and pressure. Obtain the dimensionless groups that charactrize this probl..
At an angle of α=30°with the vertical, a 5kg sphere is suspended on a string of length .8m with a initial velocity of 1.2m/s, it colides with wedge B. ε=.7 between the .9kg wedge and sphere
Determine the final phase of the water in the tank. Calculate the final temperature (oF) of the water in the tank.
A turbine discharges water at 0.4 m3/s under a head of 10.50 m and with an overall efficiency of 80 %. determine what is The power developed.
A race car C is being tracked via telemetry. The on-board acclerometer records and acceleration level of -.7get+.5gen. If you know that the v at this instant is 200km/hr, what is the tracks radius of curvature at this instant?
calculate the alkalinity as CaC03 of water that contains 85mg/l of HCO3, 120 mg/l of CO3 and 2 m/l of OH.
