Determine the minimum force P to prevent the 30 kg uniform rod AB from sliding. The contact surface at B is smooth, whereas the coefficient of static friction between the rod and the wall at A is μs = 0.3.

A specimen has circular cross-sectional area with initial diameter d = 26 mm and a gauge length Lo = 200 mm. A force P = 127 kN elongates the specimen by delta = 3 x 10^-1 mm.

Suppose you have two boxes in front of you. One box contains a Thevenin Equivalent (voltage source in series with a resistor) and the other box contains a Norton Equivalent (current source in parallel with a resistor).

The animation shows the circuit inside a speaker. The speaker cone vibrates as the current changes direction. This creates sound waves. Explain how the electromagnet causes movement back and forth as the electric current changes.
