A force of 15.3 N lies in this plane and is exerted to the square. Determine the magnitude of the maximum torque which such a force could generate?
The vibration of tympanic membrane in the human ear (eardrum) can be explained as a harmonic motion. Supposing a mass of 20.6 mg and a period of vibration of 1.72 ms, determine the natural vibration
At time t = 0 the object is pulled to a distance of 28.1 cm from its equilibrium position (which you might select conveniently at x = 0). The surface on which the object moves is frictionless.
determine how long does it take to fully unwind the hose from the reel? Avoid the mass of the hose, and suppose which the hose unwinds devoid of slipping.
An ac generator generating 10 V (rms) at 200 rad/s is joined in series having a 50 ohm resistor, a 400 mH inductor, and a 200-µF capacitor. The rms voltage (in volts) across the capacitor is:
