Centre of mass of two unifrom rods of same length but made up of different materials & kept as shown, if the meeting point is the origin of co-ordinates :-

A

`(L//2, L//2)`

B

`(2L//3, L//2)`

C

`(L//3, L//3)`

D

`(L//3, L//6)`

Text Solution

Verified by Experts

The correct Answer is:
D
Equation of line joining the CM of two rods
`(x)/(L//2) + (y)/(L//2) = 1`
coordinate `((L)/(3),(L)/(6))` satisfies this equation.

A brass rod of length 50 cm and diameter 3.0 mm is joined to a steel rod of the same length and diameter. What is the change in length of the combined rod at 250 ^(@) C . if the original lengths are at 40.0 ^(@) C ? Is there a "thermal stress developed at the junction ? The ends of the rod are free to expand (Co-efficient of linear expansion of brass = 2.0 xx 10^(-5) K^(-1) , " steel " = 1.2 xx 10^(-5) K^(-1)) .

In a vernier callipers the main scale and the vernier scale are made up different materials. When the room temperature increases by DeltaT^(@)C , it is found the reading of the instrument remains the same. Earlier it was observed that the front edge of the wooden rod placed for measurement crossed the N^(th) main scale division and N + 2 MSD coincided with the 2nd VSD. Initially, 10 VSD coincided with 9MSD. If coefficient of linear expansion of the main scale is alpha_(1) and that of the vernier scale is alpha_(2) then what is the value of alpha_(1)//alpha_(2) ? (Ignore the expansion of the rod on heating)
