Question
1-An object has a moment of inertia of 9.99 kg*m2, and a torque of 10.25 N*m is applied on it. What is the angular acceleration of the object in unit of rad/s?
2- In this lab, we will determine the mass of a disk using two different methods. The mass value measured by a mass scale is 500.96 grams, determined by calculation is 536.57 grams. What is percent error of the calculated value?
(Percent error can be a positive, negative, or zero value. Please refer to the lab handout)
3-
In this lab, we measured moment of inertia using a 350 gram and 500 gram hanging mass, respectively. The values found were 0.93 and 0.96 kg.m2. What is percent difference of those values?
(Percent difference can be a positive or zero value, please refer to the lab handout)
4-The mass of two objects are M1 and M2 respectively, and M2 > M1. M2 must have a larger moment of inertia than M1.
True
False
Explanation / Answer
1) Apply, T = I*alfa
==> alfa = T/I
= 10.25/9.99
= 1.026 rad/s^2
2) error % = (536.57 - 500.96)/500.96 *100
= 7.1%
3) 0.96 - 0.93 = 0.03
persentage difference = 0.03/0.93*100
= 3.22%
4) Flase
Beacuse, moment of Inertia does not depend only on mass. it depends on shape of the body also.
