Explanation:
Given that,
Mass of disk = 1.2 kg
Radius = 0.07 m
Radius of rod = 0.11 m
Mass of small disk = 0.5 kg
Force = 29 N
Time t = 0.022 s
Distance d= 0.039 m
(I). We need to calculate the speed of the apparatus
Using work energy theorem
Where, m = total mass
v = velocity
F = force
d = distance
Put the value into the formula
(b). We need to calculate the angular speed of the apparatus
Using formula of torque
We need to calculate the angular speed of the apparatus
Using equation of angular motion
Put the value into the formula
(c). We need to calculate the angular speed of the apparatus
Using equation of angular motion
Put the value into the formula
Hence, This is required equation.
Solution:
f ( t )= 20 S ( t ) + 55/30 tS ( t )− 55/30 ( t − 30 ) S ( t − 30 )
• Taking the Laplace Transform:
F ( s ) = 20/s + 55/30 ( 1/s^2 ) – 55/30 ( 1/s^2) e^-30s = 20/s + 55/30 ( 1/s^2 ) ( 1 – e^-30s)
f ( t )= 20 S ( t ) + 55/30 tS ( t )− 55/30 ( t − 30 ) S ( t − 30 )
• Taking the Laplace Transform:
F ( s ) = 20/s + 55/30 ( 1/s^2 ) – 55/30 ( 1/s^2) e^-30s = 20/s + 55/30 ( 1/s^2 ) ( 1 – e^-30s)
