In a dynamically equivalent system, a uniformly distributed mass is divided into
View Answer Explanation
A crank and slotted lever mechanism used in a shaper has a centre distance of 300 mm between the centre of oscillation of the slotted lever and the centre of rotation of the crank. The radius of the crank is 120 mm. Find the ratio of the time of cutting to the time of return stroke.
The magnitude of velocities of the points on a rigid link is directly proportional to the distances from the points to the instantaneous centre.
The velocity of the instantaneous centre relative to any third rigid link will be different.
When the pin connects one sliding member and the other turning member, the angular velocity of the sliding member is __________
In a slider crank mechanism, the velocity of piston becomes maximum when
What is the purpose of double hooke’s joint?
Double hooke’s joint can be used to keep the angular velocity of the shaft constant.
Two shafts having an included angle of 150° are connected by a Hooke’s joint. The driving shaft runs at a uniform speed of 1500 r.p.m. The driven shaft carries a flywheel of mass 12 kg and 100 mm radius of gyration. Using the above data, calculate the maximum angular acceleration of the driven shaft in rad/s².

Two shafts connected by a Hooke’s joint have an angle of 18 degrees between the axes. Find the angle through which it should be turned to get the velocity ratio maximum.
