4 Oscillations In The Elevator Gravity Stretches An Elastic Thin Wire Of 1 M Length By 15 5 Mm As 500 G Mass Is Attache 1 (39.13 KiB) Viewed 13 times

#4 Oscillations in the elevator Gravity stretches an elastic thin wire of 1 m length by 15.5 mm as 500 g mass is attached. Determine the oscillation period, if the wire is initially stretched a little more. Which length does a pendulum thread need to have, if the pendulum should have the same period? Now put the pendulum into an elevator. The elevator accelerates and is going up: The velocity increases linearly in time during the first 3 s until reaching 24 m/s. Sketch the deflections of the pendulum versus time t in the elevator frame of reference 0.5 s before the elevator starts until 0.5 s after the start. The initial deflection is 1°. How will the deflection amplitude change qualitatively? What sort of motions of the pendulum can be observed if the elevator is going down with 9.81 m/s²?
