Four identical uniform thin rods, each of mass m and length l are joined to a common point O as shown in the figure. Moment of inertia of the system about an axis passing through O and lying in the plane of rods is

Two rods (one semi-circular and other straight) of same material and of same cross-sectional area are joined as shown in the figure. The point A and B are maintained at different temperature. Find the ratio of the heat transferred through a cross-section of a semi-circular rod to the heat transferred through a cross section of the straight rod in a given time.

Two similar rods are joined as shown in figure. Then temperature of junction is (assume no heat loss through lateral surface of rod and temperatures at the ends are shown in steady state )

Two similar rods are joined as shown in figure. Then temperature of junction is (assume no heat loss through lateral surface of rod and temperatures at the ends are shown in steady state )

Heat is flowing through two cylindrical rods made of same materials whose ends are maintained at similar temperature. If diameters of the rods are in ratio 1:2 and lengths in ratio 2:1 , then the ratio of thermal current through them in steady state is:
