A resistor R = 1 k Ohm an inductor L = 1 mH and a capacitor C = 1 mu Fare used in a circuit which is driven by a voltage source vs (t) = 10 sin (10 5 t + 45 degree) (warning: note the input is a sine function not a cosine function. What is the phasor corresponding to the voltage source? Express it in the polar form A < B and write your answer as "A B" without the quotation marks.

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

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

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.
