A copper wire of 1mm diameter is stretched by applying a force of 10N. Find the stress in the wire
1 Answer
Vikas TU
Stress = Force/ Area
Area here it is cross – section part.
Hence,
A = pi*(1/2)^2 = > pi/4 mm^2.
Stress = 10/(pi/4) = > 40/pi = > 12.73 N/mm^2.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
