One form of which consists of three equal weights joined by equal length ropes. The gaucho holds on to one weight spinning the bolas overhead. When the bolas is cast the weights cause the configuration to change. A typical bolas consists of three one pound weights joined by three 2 feet 4 inch lengths of rope. Before casting the weights have a velocity of 60 RPM. What are the rotational velocity in RPM and linear velocities of the weights after throwing? If the radius of the weight is small compared to the radius of the motion, the mass moment of a weight is I = md2 where d is the distance from rotation center to weight.
If the front edge of a contaminant plume is perfectly straight, how long would it take to travel to Well 1 after first arriving (simultaneously) at Wells 2 and 3, assuming that the contaminant plume travels only half as fast as the groundwater flo..
A steel pipe carries an industrial oil under pressure. The steel pipe inside diameter is 36 in, the pressure head on the fluid is 383.0 ft. A)- Find the internal fluid pressure in psi
Light-Voice Controlling System. We are planning to design a new light-voice controlling system. The voices will basically coordinate the crossing of a road by blind people. Suppose the crossing will be operated by two coordinated systems
A sand sample has a porosity of 38% and specific gravity of solids of 2.66. Find the void ratio and wet unit weight in lb / ft3 if the degree of saturation is 35%.
A light rail route has 2 terminals and 4 intermediate stations. The demand (passengers/hr) for morning peak hour is: North Terminal Station 1 Station 2 Station 3 Station 4 South Terminal
The VMA of a mixture is 15.0% and the air voids are 4.0%.If the aggregate has a specific gravity (bulk dry) of 2.700 g/cm3 and percent binder absorbed (by the mass of aggregate) is 0.5%, calculate the asphalt content by weight of mix.
each month the splendid dry cleaning company buys one barrel ( 42 gal., 0.160 m^3) of tetrachloroethylene (C2Cl4) (M.W.= 166, p= 1.594 g/cm^3) ninety percent of the fluid is lost to the atmosphere and 10% remains as residue to be disposed of.
Person spining has his arms outward. The moment of inertia is 52kg*m^2 and ang. speed 3.80 revolutions/ second. if the persons arms are down. moment of inertia goes to 35kg*m^2. find the new angular speed
determine critical depth in a circular pipe of 36 inches diameter and roughness coefficient of 0.015 The flow rate is 15 cfs , So = 0.002
You are the winner of a sweepstakes and given a choice of a one-time payment of $1,000,000 or a guaranteed $80,000 per year for 20 years. Assume that you will collect all 20 years regardless of health condition.
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..
A left-turn movement has a maximum arrival rate of 200 veh/h. The saturation flow of this movement is 1400 veh/h. For this approach, the yellow time is 4 seconds, all red time is 2 seconds and total lost time is 3 seconds.
