Question 1
In a slider crank mechanism the crank rotates with uniform angular velocity. The angular acceleration of connecting rod will zero when the____.
Question 2
Maximum angular velocity of the connecting rod with a crank to connecting rod ratio 1:5 for a crank speed of 3000 rpm is around:
Question 3
Find the maximum angular velocity of connecting rod when crank rotates at 2000 rpm. Length of connecting rod and crank are 120 mm and 20 mm respectively
Question 4
In a slider-bar mechanism, when does the connecting rod have zero angular velocity?
Question 5
The angular velocity of the connecting rod in a single slider crank mechanism is given by
Question 6
The piston velocity at the position when the crank makes an angle of 90o with the line of slider is equal to
Question 7
A reciprocating engine is rotating with an angular velocity of 25 rad/s. if the length of the connecting rod is 100 mm and radius of the crank is halved than the length of the connecting rod. At an instant when the crank is at angle 90 degree from the line of action of the stroke, What should be the acceleration of the slider in m/s2.
Question 8
The acceleration of the piston at the position when the crank makes an angle of 90o with the line of slider is equal to
(Consider the length of connecting rod as 250 mm and crank radius as 50 mm)
where R is crank radius and 
is angular velocity of crank
