- Three uniform thin aluminum rods each of length 2 m form an equilateral triangle P Q R as shown in the figure. The mid point of the rod P Q is at the origin of the coordinate system. If the temperature of the system of rods increases by 50° C, the increase in y -coordinate of the centre of mass of the system of the rods is ............ mm. (Coefficient of volume expansion of aluminium =12 √3 × 10-6 K -1 )
Q.
Three uniform thin aluminum rods each of length form an equilateral triangle as shown in the figure. The mid point of the rod is at the origin of the coordinate system. If the temperature of the system of rods increases by , the increase in -coordinate of the centre of mass of the system of the rods is ............ . (Coefficient of volume expansion of aluminium )
