What does a negative moment of inertia mean?

Physics
1 answer:
nydimaria [60]3 years ago

When we are talking about simple Ixx or Iyyvalues, then yes these will always be positive. However, when talking about moment products like Ixy, these will not necessarily be positive, mainly when holes have been cut in these cross sections.

When the holes are cut in, those moments then become negative, and due to the parallel axis theorem sometimes these negative values actually become larger than the initial value, and the moment then becomes negative.

Natalka [10]

Answer:

a) Tc = 750 [N]  ;b) See the explanation below.

Explanation:

To solve this problem, we first need a graphical explanation of this, as well as knowing the corresponding questions. Therefore, a search was carried out in google, in the attached image we will find a graphical description of the problem.

b)

The solution of this type of problem corresponds to the use of Newton's third law, applying static which tells us that the sum of the forces in a system in equilibrium without movement must be equal to zero.

a)

In this way we can find by means of a sum of forces on the y axis equal to zero:

- 850 - 450 + 550 + Tc = 0

Tc = 750 [N]
