Q1) Following is the data for a circular arc cam working with a flat faced reciprocating follower : Minimum radius of the cam 28.5 mm; Total angle of cam action 110°; the lift of the follower is 13 mm, Radius of the circular arc 80 mm ; Nose radius = 3 mm. 1. Find the distance of the Radius of the circular arc; 2. Draw the profile of the cam to full scale; 3. Find the angle through which the cam turns when the point of contact moves from the junction of minimum radius arc and circular arc to the junction of nose radius arc and circular arc 4. Find the velocity and acceleration of the follower when the cam has turned through an angle of 10°.( The angle is measured from the point where the follower just starts moving away from the cam.) The angular velocity of the cam is 200 rpm.

Question
Q1) Following is the data for a circular arc cam working with a flat faced
reciprocating follower :
Minimum radius of the cam 28.5 mm; Total angle of cam action =
110° ; the lift of the follower is 13 mm, Radius of the circular arc = 80
mm ; Nose radius = 3 mm.
1. Find the distance of the Radius of the circular arc ;
2. Draw the profile of the cam to full scale;
3. Find the angle through which the cam turns when the point of contact
moves from the junction of minimum radius arc and circular arc to the
junction of nose radius are and circular arc
4. Find the velocity and acceleration of the follower when the cam has
turned through an angle of 10°.( The angle is measured from the point
where the follower just starts moving away from the cam.) The angular
velocity of the cam is 200 rpm.
