Problem 19
The slotted fork is rotating about O at the rate 0 'which is increasing at 0 " when 0 = 0,.
Determine the radial and transverse components of the velocity and acceleration of the pin A
at this instant. The path is defined by the spiral groove r= 25(5 + 0 /t) mm., where 0 is in
radians.
Given:
rad
= 3
rad
e" = 2
b = 125 mm
r = (b +c 0)-
25
mm
01 = 2 n rad
Solution:
e = 01
