Answer:
The tension in the string T is 1.96 N
Step-by-step explanation:
Given: A cylinder of mass 0.6 kg and radius R is falling under gravity
To find: The tension in the thread
Solution:
A cylinder of mass 0.6 kg and radius R is falling under gravity
Therefore
The force of gravity acting on an object is its weight, which may be calculated by multiplying its mass by its gravitational acceleration.
w= mg
Considering translation, we get the equation as
mg - T = ma
Considering rotation, we get the equation as
T × R = I ×d
T × R = ×d
T =
It is given that Radius R is falling under gravity without slipping.
Therefore for no slip condition the acceleration is
⇒ a = dR
⇒ d =
Tension in the string is
⇒ T =
⇒ T =
⇒ T =
Tension in the rotation
⇒ mg - T= ma
⇒ mg -
⇒ mg =
⇒ g =
a =
Substitute acceleration in tension in the string
⇒ T =
⇒ T =
T =
T =
T = 1.96 N
T = 1.96 N
Final answer:
The tension in the thread is 1.96 N
