A square aluminum rod is 1 m long and 5 mm on edge. What must be the radiys of another aluminum rod whose length is 1 m and which has the same reistance as that of square Aluminum rod ?

A steel rod of length 20 3/26 is cut down from a rod of length 56 1/5 what when is the remaining length of the rod?

A steel rod of length 20 3/26 is cut out from a rod of length 56 1/5 . What then is the remaining length of the rod?

The length of a rod is 5 xx 10^(2) m , the order of magnitude of the length of the rod is

A brass rod is 69.5 cm long and an aluminum rod is 49.0 cm long when both rods are at an initial temperature of 0^(@)C . The rods are placed in line with a gap of 1.5mm between them. The distance between the far ends of the rods remains same throughout. the temperapure is raised until the two rods are barely in contact. The coefficients of linear expansion of brass and aluminum are 2.0xx10^(-5)K^(-1) and 2.4xx10^(-5)K^(-1) respectively. In figure, the temperature at which contact of the rods barely occurs, in .^(@)C is closest to: z

A square frame is made rods each of mass m and length l . The moment of inertia of the square about its face diagonal is

A silver cylindrical rod has a length of 0.5 m and radius of 0.4 m, find the density of the rod, if its mass is 2640 kg.

What will be the length of the longest rod that can fit in 12m long, 4 m wide and 3m high- room.

15 small rods, each of length 23 2/7 m are joined to make a big rod. What then is the length of the big rod?

The mass of an aluminium rod varies directly with its length. If a 16 cm long rod has a mass of 192 g, find the length of the rod whose mass is 105 g.
