Question

If pressure angle in a cam and follower mechanism increases

Select the correct answer from the codes given:

• A. Only 1 and 2 are correct
• B. 1, 2 and 3 are correct
• C. Only 2, and 3 are correct
• D. None of these

Answer 1

The correct option is B 1, 2 and 3 are correct


$\text{Side thrust}=P\sin \varphi$

$\text{This component which is perpendicular to line of stroke tends to bend the follower and produces friction and wear in guides.}$

$\text{as}\varphi \uparrow ,\text{side thrust increases, so friction and wear increases.}$

$\text{Where}\varphi =\text{pressure angle}$
