Springs are simple devices that are commonly used. It is used in shock absorbers in automobiles, in push-back ballpoint pens, in electrical measuring instruments, etc. The spring possesses a simple property by the virtue of which, when compressed or elongated, it tries to ..

Consider a massless spring of natural length 'l', one end of which is fastened to a wall. The other end is attached to a block, which is slowly pulled on a smooth horizontal surface, to extend the spring. If we take the spring as a system, when it is elongated by a dis..

The number of ATM transactions of a bank per day were recorded at 12 locations in a city. The mean of the sample was 88.5 transactions, with a sample standard deviation of 42. Find the 98% confidence interval of the true mean. => 19.06 < μ < 157.94 or 78.99 < μ &l..

According to Hooke's Law, the force needed to stretch a spring is proportional to the length to which the spring is stretched. If 42 pounds stretches a spring to 3 inches, then how much will the spring be stretched by a force of 53 pounds? => 14 inches or 3.7..
