Calculate the torque on the square plate of the A square plate of mas

1.	Calculate the torque on the square plate of the A square plate of mass 120 g and edge 5.0 cm rotates about one of the edges. If it has a uniform angular acceleration of 0.20 rad/s². if it rotates about a diagonal with the same angular acceleration.?
Answer» Given in the QUESTION :- Angular acceleration , α = 0.20 Mass M = 120 G or 0.12 kg Edge a = 5.0 cm or 0.05 m Moment of inertia of PLATE when LINE PASSING by centre and parallel to the edge $I =\frac{Ma^2}{12}$ Now, Torque (plate) T = Iα $\frac{Ma^2}{12} * 0.20$ = ⇒ 0.12 × 0.05² × (0.20/12) ⇒ 0.01 × 0.05 × 0.01 *⇒ 0.5 x 10⁻⁵ N.m* Hope it Helps :-)

Answer»

Given in the QUESTION :-

Angular acceleration , α = 0.20

Mass M = 120 G or 0.12 kg

Edge a = 5.0 cm or 0.05 m

Moment of inertia of PLATE when LINE PASSING by centre and parallel to the edge

$I =\frac{Ma^2}{12}$

Now, Torque (plate)

T = Iα

$\frac{Ma^2}{12} * 0.20$ =

⇒ 0.12 × 0.05² × (0.20/12)

⇒ 0.01 × 0.05 × 0.01

⇒ 0.5 x 10⁻⁵ N.m

Hope it Helps :-)
