What are t test and F test In which situation these are applied?

Both are parametric test.
The t-test uses a test statistic that is related to the sample mean(s) and is used to compare that with the mean of another sample or some population.
The F-test uses a test statistic that is related to the sample variance and is used to compare that with the variance of another sample or some population.
Both tests require identical independently distributed random variables. This ensures that the relevant test statistics are approximately normally distributed.

What statistic measures data variability in both groups in an independent t-test?
It appears that you might be referring to a situation in which Welch's t-test can be applied. Since it would be excruciating to write the required formulae here on answers.com let me refer you to the wikipedia page.

When data is normally distributed which test can be taken?
The answer depends on what is being tested: the t-test, F-test, Chi-square, Z-test are all commonly used with the Normal distribution. There are many others.
Is the f distribution same as z distribution?
Each different t-distribution is defined by which of the following? @Answer found in section 4.3 The One-sample t-Test, in Statistics for Managers

What equation can be used to find power P in terms of force F distance d and time t?
The equation P = F * d / t can be used to find power P in terms of force F, distance d, and time t. Power is equal to the force applied multiplied by the distance over which the force is applied, divided by the time taken to do the work.

What is F ratio?
Computing F-ratioThe F-ratio is used to determine whether the variances in two independent samples are equal. If the F-ratio is not statistically significant, you may assume there is homogeneity of variance and employ the standard t-test for the difference of means. If the F-ratio is statistically significant, use an alternative t-test computation such as the Cochran and Cox method.

Which has a greater torque a perpendicular force applied at the end of a wrench handle or an equal force applied in the same direction near the middle of the handle?
the perpendicular force applied at the end of a wrench handle. Because torque= Fd / T = F d cos θ therefore the greater the distance the greater the torque. T=torque F=force d=distance cos=cosine θ=theta
