Time period of the simple pendulum is denoted by T The formula for the period, T, is  where  is the length of the pendulum measured from the pivot point to the bob's center of gravity. |
The Scientist does not study nature because it is useful; he studies it because he delights in it, & he delights in it because it is beautiful. If nature were not beautiful, it would not be worth knowing, life would not be worth living. Ofcourse I do not here speak of that beauty that strikes the senses, the beauty of qualities & appearances; not that I undervalue such beauty, far from it, but it has nothing to do with science; I mean that profounder beauty which comes from the harmoniuos order of the parts, & which a pure intelligence can grasp. |

and 1 more question.... a spring of force constant k is cut into 2 equal parts,which are then joined parallel to each other,.the force constant of the combination wil be???

Two springs of spring constants k1 & k2 are combined in parallel then effective total spring constant is k(parallel) = k1 + k2. But if the two springs of are combined in series then effective sping constant is given by 1/k(series) = (1/k1) + (1/k2) One might say that the spring constants will add like a capacitor network, not like a resistor network. That is, the spring constants of a series network are summed as the inverse. The spring constants of a parallel network are summed directly.

In your case if the spring constant = k Then on dividing the spring in two equal parts will increase the spring constant by a factor of 2 So spring constants of two equal halves is = 2k So on parallel combination of these two springs the effective spring constant is kparallel = 2k + 2k = 4k

That is true and if spring is divided in n equal parts then the spring constatnt of each spring is increased by n times of the original spring.
Please rate me if i am right.
