FORMULAE SUMMARY
Before
proceeding to numerical problems, the formulae that are to be used are
summarised and presented in Table 3.2.
Table 3.2. Formulae summary
Notations used:
L
= Lift or stroke of the follower in m,
θO
= Outward angle (or angle of ascent) in radians,
θr
= Return angle (or angle of descent) in radians,
ω = 2π
Ν/60 = Angular velocity of cam in rad/s, and
N
= Speed of cam in rpm
Note:
1.
In the above formulas, the values of angle θO and θr
must be in radians
2.
In the above formulas, (+) or (-) sign is used to indicate the direction of
characteristics (see the velocity, acceleration and jerk curves in Figs.3.14,
3.17, 3.19 and 3.21 for better understanding).
