Equilibrium and Stability
Equilibrium and Stability - What makes a body stable? An object is said to be stable if it is steady and well balanced so that when it is pushed slightly it does not topple or fall off easily. Let us try to do a simple experiment or derive the conditions for stability. Experiment 1: Stick..

Two identical balls, each of mass 0.1 x 10 - 3 kg, carry identical charges and are suspended by two threads of equal length. At equilibrium, they position themselves as shown in the figure below. Calculate the charge on either ball. ..

When a steady current passes through a moving coil galvanometer, the coil undergoes a torque and does not come to equilibrium position instantly. Hence the coil is wound over a metallic frame so that the eddy currents produced in the frame can damp the oscillation and brings th..
Application of Eddy Currents

Formation of stationary waves explained graphically
Figure(a) shows two sinusoidal waves A and B having the same amplitude and frequency, traveling in opposite directions. At an instant of time t = 0, the resultant displacement graph is a straight line. All the particles of the medium affected by the two waves are at their equilibrium ..

Characteristics of SHM - It is a motion along a straight line. The body moves back and forth with respect to a mean position. The body returns to a given point in the path with the same velocity after regular intervals of time. The acceleration is directly proportional to its displacement from..
Simple Harmonic Motion
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, the defor..

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 very light s..

The maximum displacement of the particle executing SHM from the equilibrium position is known as the amplitude. It will be equal to the radius of the circle of reference. Therefore, the total range of motion is 2..

When a current is passed through the coil in the direction PQRS, then the coil experiences a torque t = NIBA sin a Since the magnified field is radial the plane of the coil is parallel to the magnetic field such that a = 90 o and hence t = NIBA. The coil rotates and the phosphor bronz..

Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
I think the tutors knew their stuff really well and was very helpful. math was actually something I dread.not anymore ,Thank you Tutor Vista - jennifer,New york
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
Looking for More Help!
