Explain the formation os stationary waves by analytical method. Show the formation of stationary wave diagramatically. A mass of 1 kg is hung from a steel wire of radius 0.5 mm and length 4 m. Calculate the extension produced. What should be the area of cross-section of the wire so that elastic limit is not exceeded? Change in radius is negligible ? Given g=9.8m//s^(2) , Elastic limit of steel is 2.4xx10^(8)N//m^(2) , Y for steel (Y_("steel"))=20xx10^(10)N//m^(2),pi=3.142 ).
A steel wire of length 1m, and radius 0.1mm is elongated by 1mm due to a weight of 3.14kg. If g = 10 m//s^(2) , the Young's modulus of the steel wire will be
A fine steel wire of length 4 m is fixed rigidly in a heavy brass frame as ashown in figure . It is just taut at 20^(@)C . The tensile stress developed in steel wire it whole system is heated to 120^(@)C is :- ( Given alpha _("brass") = 1.8 xx 10^(-5) .^(@)C^(-1), alpha_("steel") = 1.2 xx 10^(-5) .^(@)C, Y_("steel") = 2 xx 10^(11) Nm^(-2), Y_("brass")= 1.7xx10^(7) Nm^(-2) )
A load of 4.0 kg is suspended from a celling through a streel wire of length 2.0 m and radius 2.0 mm. It is found that the length of the wire increases by 0.031 mm as equilibrium is achieved. Taking g = 3.1 pi ms^(-2) the Young's modulus of steel is
Calculate the value of stress on a wire of steel having radius of 2 mm, when 10 kN of force is applied on it.
A wire of length 2 ,m and radius 2 mm is stretched by 2.5 mm when a load of 5 kg is suspended from it Another wire of the same material put of length 1 m and radius 1 mm is attached below the load and a load of 3kg is suspended from this wire what is the total increase in length and what are the individual exensions of the wirs ?
A steel wire of diameter 0.5 and Young’s modulus 210 carries a load of mass . The length of the wire with the load is 1.0. A vernier scale with 10 divisions is attached to the end of this wire. Next to the steel wire is a reference wire to which a main scale, of least count 1.0 , is attached. The 10 divisions of the vernier scale correspond to 9 divisions of the main scale. Initially, the zero of vernier scale coincides with the zero of main scale. If the load on the steel wire is increased by 1.2 kg, the vernier scale division which coincides with a main scale division is __________. Take g = 10 m s^(-2) and pi =3.2 .
