A bar of length l is clamped at x=0 and loaded with a mass mat x=l.(a) apply these boundary conditions to equation x=A e^(wt+kx)+Be^(wt- kx) and thereby determine an equation from which the fundamental frequency of longitudinal vibrations may be computed.(b) Determine the fundamental frequency of such a system composed of a steel bar of0.5-mlength and 0.0001 m2 cross-sectional area to which is fastened a mass of 0.15 kg.(c) When a bar in vibrating in this manner, what position along tghe bar haste maximum longitudinal displacement amplitude?
The rotational velocity of a merry go round is increased at a constant rate from 1.5 rad/s to 3.5 rad/s in a time of 9.5 s. What is the rotational acceleration of the merry-go-

In the arrangement shown in figure, an object can be hung from a string (with linear mass density µ = 0.002 00 kg/m) that passes over a light pulley. The string is connected to a v
The points of maximum amplitude are called as antinodes. At ends density and air pressure both are very low.
For the system shown below the gain, G, of block A is variable and can be set as low as 100 and as high as 500. The only problem with block A is that its gain fluctuates with high
Q. How can we increase the current sensitivity of a galvanometer? The current sensitivity of a galvanometer is able to be increased by (i) Rising the number of turns (ii
