Description : Explain whether there is acceleration of a rotating object at a balanced speed in a circular motion ?
Last Answer : : In a circular path, there is no acceleration of the rotating object at a balanced speed The rate of change of unequal velocity is called acceleration. So if the velocity is balanced , there will be no acceleration Be it in a circular way or in a straight way.
Description : What is balanced acceleration ?
Last Answer : If the velocity of an object keeps increasing at the same rate all the time in a certain direction, then the rate of increase of that velocity is called balanced acceleration.
Description : It is easier to carry two buckets of water in one hand each, than to carry only one in one hand because – (1) weights of buckets are balanced (2) centre of gravity falls within the body (3) centre of gravity and centre of equilibrium fall within the feet (4) resultant weight of buckets is zero
Last Answer : (3) centre of gravity and centre of equilibrium fall within the feet Explanation: When the buckets containing equal amount of water are held in both hands, weight is spaced out more evenly than it ... centre of gravity and the centre of equilibrium should fall, in the present case, within the feet.
Description : A man inside an artificial satellite feels weightlessness because the force of attraction due to earth is – (1) zero at that place (2) is balanced by the force of attraction due to moon (3) equal to the centripetal force (4) non-effective due to particular design of the satellite
Last Answer : (1) zero at that place Explanation: Earth attracts all bodies towards its centre. The acceleration produced in the body due to attraction force of earth on it is called the acceleration due to ... and centrifugal force which cancel out each other with the resultant force acting on him being zero.

Description : Rotor shaft of a large electric motor supported between short bearings at both ends shows a deflection of 1.8 mm in middle of motor. Assuming rotor to be perfectly balanced and supported at knife edges at both ends, likely critical speed (rpm) of shaft isA 350 B 4430 C 705 D 2810
Last Answer : C 705
Description : An aircraft has a stalling speed in level flight of 70kt IAS. In a 60° balanced turn, the stalling speed would be: a. 76kt b. 84kt c. 99kt d. 140kt
Last Answer : c. 99kt

Last Answer : b)1000-1200rpm
Description : A balanced three-phase, 50 Hz voltage is applied to a 3 phase, 4 pole, induction motor. When the motor is delivering rated output, the slip is found to be 0.05. The speed of the rotor m.m.f. relative to the rotor structure is (A) 1500 r.p.m. (B) 1425 r.p.m. (C) 25 r.p.m. (D) 75 r.p.m.
Last Answer : (D) 75 r.p.m.
