PHYSICS 6B Ch.11 Worksheet Solutions clas.ucsb.edu/staff/vince/ 1) In a design for a piece of medical apparatus, you need a material that is easily compressed when a pressure is applied to it. Should the bulk modulus of the material be large or small ? 2) Two rods of equal length (0.5m) and diameter (2.0 cm) are placed end to end. One rod is aluminum, and the other is made of brass. A compressive force of 10,000 N is applied. a) Which rod undergoes a greater change in length? b) Calculate the total change in the length of the two rods. Y AL =7x10 10 Pa; Y BR =9.1x10 10 Pa Aluminum compresses more . Use our formula for both rods. Aluminum Rod: Brass Rod: Total change is 4·10 -4 m 3) The processing “speed” of a computer refers to the number of binary operations it can perform in one second, so it is really a frequency. If the processor of a personal computer operates at 2.50GHz, how much time is required for one processing cycle? We need the period, which is the reciprocal of the frequency.
