The correct Answer is:
B
Original length `=2m` Increase in length `=1cm=1xx10^(-2)m` Longitudinal strain`= ("Increase in length")/("Original length")` `=(1xx10^(-2)m)/(2m)=5xx10^(-3)`
Steel wire of length 'L' at 40^@C is suspended from the ceiling and then a mass 'm' is hung from its free end. The wire is cooled down from 40^@C to 30^@C to regain its original length 'L'. The coefficient of linear thermal expansion of the steel is 10^-5//^@C , Young's modulus of steel is 10^11 N//m^2 and radius of the wire is 1mm. Assume that L gt gt diametere of the wire. Then the value of 'm' in kg is nearly
3 m long copper wire is stretched to increase its length by 0.3 cm. The lateral strain produced in the wire is,
A copper wire and a steel wire of the same length and same cross-section are joined end to end to form a composite wire. The composite wire is hung form a rigid support and a load is suspended form the other end. If the increses in length of the composite wire is 2.4mm . then the increases in lenghts of steel and copper wires are
A uniform rod of length l and mass m is hung from, strings of equal length from a ceiling as shown in figure. Determine the tensions in the strings?
A copper wire and a steel wire of same length and same cross-section are joined end to end. The compositive wire is hung from a rigid support and a load is suspended form the free end. The increase in length of the compositive wire is 4 mm. The increase in copper wire will be (Y_(copper)=1.2xx10^(11)N//m^(2),Y_(steel)=2xx10^(11)N//m^(2))
At 40^(@)C a brass wire of 1mm radius is hung from the ceiling. A small mass, M is hung from the free end of the wire. When the wire is cooled down from 40^(@)C to 20^(@)C it regains its original length of 0.2 m the value of M is close to (coefficient of linear expansion and young's modulus of brass are 10^(-5)//.^(@)C and 10^(11)//N//m^(2) respectively g=10ms^(-2))
A metal wire of length L is suspended vertically from a rigid support. When a bob of mass M is attached to the lower end of wire, the elongation of the wire is l:
A 5 metre long wire is fixed to the ceiling. A weight of 10 kg is hung at the lower end at is 1 metre above the floor. The wire was alongated by 1 mm. The energy stored in the wire due to stretching is
An Aluminum and Copper wire of same cross sectional area but having lengths in the ratio 2:3 are joined end to end. This composite wire is hung form a rigid support and a load is suspended form the free end. If the increases in length of the composite wire is 2.1mm the increses in lenghts of Aluminimum and Copper wirs are
