The following systems of periodic tasks are scheduled rate-monotonically on one processor. Determine whether each system is schedulable using a method that is fast and/or uses the least amount of information on the tasks. (a) T_1 = (2, 0.5, 4), T_2 = (3, 1.0, 10), T_1 = (5, 1.0, 10), and T_1 = (7, 0.45, 15).

What precautions should you take to prevent injuries when dealing with heavy loads?

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.

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way
