Is it possible to have damped oscillations when a system is at resonance? Explain.
Reciprocating motion uses the rotation of a motor to produce linear motion up and down or back and forth. This is how a reciprocating saw operates, as shown below. If the motor rotates at 60 Hz and has a radius of 3.0 cm,estimate the maximum speed of the saw blade as it moves up and down. This design is known as a scotch yoke.
A 2.00-kg block hangs without vibrating at the end of a spring (k = 500. N/m) that is attached to the ceiling of an elevator car.
