Theory of Machine In a screw jack, the effort required to lower the load W is given by P = W tan(α + φ) P = W tan(α - φ) P = W tan(φ - α) P = W cos(α + φ) P = W tan(α + φ) P = W tan(α - φ) P = W tan(φ - α) P = W cos(α + φ) ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a cam drive with uniform velocity follower, the sharp corners of the displacement diagram are rounded off at the beginning and at the end of each stroke. This is done Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because the uniform velocity motion is a partial parabolic motion Because of difficulty in manufacturing cam profile Because of loose contact of follower with cam surface In order to have acceleration in beginning and retardation at the end of stroke within the finite limits Because the uniform velocity motion is a partial parabolic motion Because of difficulty in manufacturing cam profile ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine When a mass of a critically damped single degree of freedom system is deflected from its equilibrium position and released, then it will Oscillate with decreasing amplitude Oscillate with constant amplitude Return to equilibrium position without oscillation Oscillate with increasing time period Oscillate with decreasing amplitude Oscillate with constant amplitude Return to equilibrium position without oscillation Oscillate with increasing time period ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Angle of descent of cam is defined as the angle Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in the highest position During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Through which the cam rotates during the period in which the follower remains in the highest position During which the follower returns to its initial position Of rotation of the cam for a definite displacement of the follower ANSWER DOWNLOAD EXAMIANS APP
