The masses of the frictionless cylinders A and B are 2.0 kg and 1.0 kg, respectively. The smallest value of the force P that will lift cylinder A off the horizontal surface is 55.5 N. Calculate the radius R of the cylinder B.
Each of the two dashpots has a viscous damping coefficient c = 58N*s/m In what ranges of speeds N can the motor be run for which the magnification factor will not exceed 2?
During an engine test on the ground, a propeller thrust T = 4000 N is generated on the 1500 kg airplane with mass center at G. The main wheels at B are locked and do not skid; the small tail wheel at A has no brake.
Points A and B are 1 km apart along a 15 cm new steel pipe. Point B is 20 m higher than A. With a flow from A to B of 0.03 m3 / s of crude oil (S= 0.82) at 10°C (µ =10-2N s/m2 ), what pressure must be maintained at A if the pressure at B is to be ..
Water at 25°C is flowing in a buried irrigation ditch below ground. Every 100 feet there is a vent line 1.o inches in inside diameter and 1.0 foot long to the outside atmosphere at 25°C.
calculate the flying height above datum for a camera having a focal length of 152.4 mm.
during the next month, the amount of water available for a city is lognormally distributed with a mean of 1 million gallons and a c.o.v. of 40%, where as the total demand is expected to follow a lognormal distribution
A 6-lane freeway horiz. alignment has a 1200’ C.L. radius going into a tangent and then a reversing 1800’ radius. How much tangent distance between the two curves is needed to meet the superelevation runoff requirements?
what are reasons for difference in the coefficient of kinetic friction on horizontal surface with a hanging mass at constant velocity compared to object one on incline
A spread footing supported on a sandy soil has been designed to support a certain column load with a factor of safety of 2.5 against bearing capacity failure. However, there is some uncertainty in both: the column load, P, and the friction angle, ?
A sample of natural glacial till was taken from below the groundwater table. The water content was found to be 52%. Estimate the wet density, dry density, buoyant density, porosity, and void ratio.
Consider the simply supported beam that has one external load applied to it. At a cross- section that cuts through the carriage bolt, there are 5 points at which the states of stress must be identified.
The maximum dry density determined in the laboratory for a quartz sand is 1800 kg/m^3. In the field, if the relative compaction is 90%, determine the hydraulic conductivity of the sand in the field compaction condition
