physics problems tension in string problems

"For a given string of constant length, the frequency of vibration is directly proportional to the square root of the tension..

In physics, the word 'string' is used in a more general sense than what it normally denotes. In olden days, musical instruments employed strings of twisted intestines of animals, such as cat-gut. Nowadays, the strings of musical instruments like the veena, vi..

When the applied force and the displacement make an angle 90 o to each other, the work done is zero. This is because cos 90 = 0. A person carrying a briefcase, moves on a horizontal road. Since, the gravitational force acts vertically downwards and the displacement of the person is in the horiz..

"For a given string under constant tension, the frequency of vibration is inversely proportional to the length of the string..

"For a string of a given length and diameter and under constant tension, the frequency is inversely proportional to the square root of the density of the material of the string..

. A reaction is the force of a surface on an object resting against it. In [Figure (b) shown above] the ladder rests against a part of the wall which is smooth, the total reaction is perpendicular (normal) to the wall as shown. But to prevent the ladder from slipping, a frictional force must act as..

Consider a body of mass 'm' tied to a string and rotated in a vertical circle of radius 'r'. The velocity (speed) of the body keeps changing. It is maximum at the bottom and a minimum at the to..

A simple pendulum is an arrangement in which a point mass is suspended by an inextensible weightless string in a uniform gravitational field. This is an ideal system which cannot be realized in practice. However, a pendulum consisting of a small but relatively heavy bob on one end of a ve..

Melde's fork is arranged such that transverse waves can be set up in the string, when it vibrates. The scale pan is removed from the string and its mass S is found in a balance. It is attached to the string again. The fork is made to vibrate by inserting the plug key ..

The restoring force in a spring (or in general, any elastic body) obeys Hooke's law. An English scientist Robert Hooke, in the year 1679, enunciated the fundamental law of elasticity in the form ut tensio sic vis which means, As the tension, so is the extension. Within the elastic limits,..
