What is the reading shown in spring balance

Text Solution

Verified by Experts

Mass spring=m
Force constant=k
Un-stretched length=I
Angular velocity=`omega`
Let .x. be the increase the length of the spring
The new length=(l+x)=r
When the spring is rotated in a horizontal circle, Spring force = centripetal force,
`kx=momega^(2)(1+x)`
`x=(momega^(2)l)/(k-momega^(2))`

Figure shows a light spring balance connected to two blocks of mass 20 kg each. The graduations in the balance measure the tension in the spring. A. What is the reading of the balance? B. Will the reading change if the balance is heavy, say 2.0 kg?

A spring balance is attached to the ceiling of a lift. When the lift is at rest spring balance reads 49 N of a body hang on it. If the lift moves: (i) Downward (ii) upward, with an acceleration of 5 ms^(-2) (iii) with a constant velocity. What will be the reading of the balance in each case?

Find the reading of th spring balance shown in figure. The elevator is going up with an accelertion of g/10, the pulley and the strng are light and the pulley is smooth.

A spring compressed by 10 cm develops a restoring force of 10 N.A body of mass 9 kg is placed on it . What is the force constant of the spring ? What is the depression in the spring under the weight of the body? What is the period of oscillation if the body is disturbed from its equilibrium position?

The reading of a spring balance corresponds to 100 N while situated at the North pole and a body is kept on it. The weight recorded on the same scale if it is shifted to the equator (take, g=10m//s^(2) and radius of the Earth R=6.4xx10^(6)m ) is:
