An engineer sets up an experiment to determine the coefficient of static friction "us" for an unknown material. She cuts the material in to a disc and places a test mass on top, L = .75m from the center, and she proceeds to spin the disc with an angular acceleration of theta-double-dot = 40t rad/s^2 counterclockwise. The engineer notes that the test mass slips at t=.2s. What is "us" (friction)?

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
