- The least count of the main scale of a screw gauge is 1 mm. The minimum number of divisions on its circular scale required to measure 5 um diameter of a wire is (a) 50 (b) 200 (c) 500 (d) 100 The pitch and the number of divisions, on the circular scale for a given screw gauge are 0.5 mm and 100, respectively. When the screw gauge is fully tightened without any object, the zero of its circular scale lies 3 divisions below the m an line. The readings of the ain scale and the circular scale for a thin sheet ar 5.5 mm un 18 respectively, the thickness of this sheet is (а) 5.950 mm (c) 5.755 mm (b) 5.725 mm (d) 5.740 mmarrow_forwardAt a temperature of 31.5 °C a 0.47-mm gap exists between the ends of the rods shown. At a later time when the temperature has reached 129.7°C, determine the change in length of the steel rod if L = 321.66 mm and M = 230 mm. Round off the final answer to four decimal places.arrow_forwardB2. Determine the resistance of an aluminium coil of 1.25 cm as diameter consists of 14800 turns and the mean length per turn is 33 cm.
