True or False?
Considering a door as a rigid body. Its angular motion happens in a plane parallel to the floor and its axis of rotation is located through the hinges.
Homework Answers
The above statement is true
Because when you apply the torque on the door ( means when you pused the door actually you are applying the torque on it ) door perform the rotational motion but not for all 360 degree . It perform the rotational motion for only 90 degree . When you push the door you will find that the door is parallel to the floor i.e door will not going to touch to the floor and the axis of rotation will be located through the hinges.
Hence given statement is true .

Part (a) [2 marks]
The angular displacement of the rigid body ranges from
θ = 0° (the vertical as shown in the figure) to θ
= 135° and can be modelled using simple harmonic motion. Assuming a
rate of 20 [reps/min], write down an expression for angular
displacement, θ [rad] as a function of time, t [s]. You may assume
that the motion starts with an angular displacement of 135°.
