1.The coupling is used to connect the two shafts together. Assuming that the shear stress in the bolts is uniform, determine the number of bolts necessary to make the maximum shear stress in the shaft equal to the shear stress in the bolts. Each bolt has a diameter d.
2.A four-wheel tractor whose operating weight is 47,877 lb is pulled up a road whose slope is +3.5% at a uniform speed. If the average tension in the towing cable is 4,860lb, what is the rolling resistance of the road?
Find the total mass, quality of steam, specific volume, specific enthalpy, and specific internal energy.
If the superelevation is .10 at the station of the PC is 17+35, what is the station of the PI and how much distance must be cleared from the center of the lane to provide adequate stopping sight distance
What is the normal depth in a 4-foot wide rectangular channel that conveys a discharge of 100 CFS and has a bed slope of 2% with a Manning's roughness coefficient of 0.025
Given the stationing in meters as (4+56) for the PC of a horizontal curve of radius R=1200 meters and angle I=22°. The azimuth of the line PC to PI as AzPC-PI = 155° 30'. A point P is to be located on the curve at stationing of 7+00.
You are given that a piece of rope is 90.5 ft long. The distance between the poles holding the rope is 90 ft. We are to find the tensions in both sides of the rope for someone walking across the rope and the deflection
Water at 120 0C with a quality of 25 % has itstemperature raised 20 0C in a constant volumeprocess. What is the new quality and pressure? Draw P-vand T-s diagrams
Assume the collector provides this energy to a thermal storage unit (a thermal reservoir) at 220oC. A heat engine receives energy from this thermal storage unit and discharges energy by heat transfer to the surroundings at 20 C
The L bracket shown below is pinned to the ground at point C and attached to a single cable at points A and D that wraps around a frictionless pulley at point B. Determine the forces acting on the bracket at point C and then tension in the cable.
A pipe contains a fitting with a minor loss coefficient equal to2.5. The pipe length = 300 meters, pipe diameter = 0.1 meters, andfriction factor = 0.018. Determine the equivalent length of pipeand fitting.
A CFL bulb that puts out as much light as a 60-W incandescent bulb might costs $10, compared to about $1 for the incandescent bulb. But CFL bulbs are expected to last (on average) 15,00 hours, compared to about 1000 hours for an incandescent bulb.
Laboratory analysis methodology to be used. Give details on the standard methods, instrument and detection limits. Standard methods for heavy metals analysis exist
A 1400-ft-long sag vertical curve (equal tangent)has a PVC at station 115 + 00 and elevation 750 ft. The initial grade is -3.5% and the final grade is +6.5%. Determine the elevation and stationing of the low point, PVI, and PVT
