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?
Question: Resultant of two forces P & Q is R. If Q is doubled R is doubled while if Q is reversed R is again doubled. Show that P:Q:R=(2) 1/2 :(3) 1/2 :(2) 1/2 .
Direct Current (DC): Such a current can be getting by connecting the two ends of a conductor to the terminals of the battery. This current doesn't change the direction

Different methods of charging a battery: There are two general methods are employed for charging are:- A) constant current system and B) constant voltage system..
Explain logarithmic decrement? Evaluate the ratio of nth amplitude with 1st amplitude in case of under damped oscillation.
Who discovered Proton? In 1886 Eugen Goldstein discovered canal rays (also called as anode rays) and showed that they were positively charged particles (ions) formed from gases
FARADAYS LAW: When the magnetic flux through the coil is made to vary, an emf is induced in the coil. The magnitude of the induced emf is proportional to the rate of change of
