Aceiling fan has 5-inch blades (so the radius of the circular fan is inches). suppose the fan turns at a rate of 2 revolutions per minute. (a) find the angular speed of the fan in radians per minute. (b) find the linear speed of the tip of a blade in inches per minute.

Aplane travels 1000 miles in 5 hours .what is the planes average speed?

The mini-refrigerator fire was most likely caused by what type of wiring?

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
