The engine of an automobile supplies 180 hp at 2500 rpm to the drive shaft. If the maximum shearing stress in the drive shaft must be limited to 6 ksi, determine the minimum diameter required (in inches) for a solid drive shaft.
Two passenger cars are traveling at 65 MPH on a highway moving in the same direction in the same lane. The cars are separated by 25 feet for every 10 MPH of their speed. The coefficient of friction (skidding resistance) between the tires and the r..

Describe in your own words the three strengthening mechanisms i.e., grain size reduction, solid solution strengthening, and strain hardening. Be sure to explain how dislocations are involved in each of the strengthening techniques.
What type of exercise takes place in a classroom setting arranged to look like an emergency operations center or in an actual emergency operations center, and involves simulation using written, telephone, and radio messaging.
A disabled automobile is pulled by means of two ropes as shown. The tension in AB is 400 lb and the angle is 20. knowing that the resultant of the resultant of the two forces applied at A is directed along the axis of the automobile, determine by ..
design a horizontal curve with a 40-degree central angle ( delta = 40) for a two-lane road with 11-ft lanes. The design speed is 70 mi/h and superelevation is limited to 0.06 ft/ft. Give the radius, degree of curvature, and length of curve that yo..
