[3 points] Question: Consider a pendulum made from a uniform, solid rod of mass M and length L attached to a hoop of mass M and

aliina [53]

Answer:

I= $\frac{4}{3}ML^2+2MR^2+2MRL$

Explanation:

We are given that

Mass of rod=M

Length of rod=L

Mass of hoop=M

Radius of hoop=R

We have to find the moment of inertia I of the pendulum about pivot depicted at the left end of the slid rod.

Moment of inertia of rod about center of mass= $\frac{1}{12}ML^2$

Moment of inertia of hoop about center of mass= $MR^2$

Moment of inertia of the pendulum about the pivot left end,I= $\frac{1}{12}ML^2+M(\frac{L}{2})^2+MR^2+M(L+R)^2$

Moment of inertia of the pendulum about the pivot left end,I= $\frac{1}{12}ML^2+\frac{1}{4}ML^2+MR^2+MR^2+ML^2+2MRL$

Moment of inertia of the pendulum about the pivot left end,I= $\frac{1+3+12}{12}ML^2+2MR^2+2MLR$

Moment of inertia of the pendulum about the pivot left end,I= $\frac{16}{12}ML^2+2MR^2+2MRL$

Moment of inertia of the pendulum about the pivot left end,I= $\frac{4}{3}ML^2+2MR^2+2MRL$

A manometer is used to measure the air pressure in a tank. The fluid used has a specific gravity of 1.25, and the differential h

Sloan [31]

Answer:

77.88 lbm/ft³

Explanation:

Given,

Specific gravity, SG = 1.25

Density of water, ρ = 62.30 lbm/ft³

density of the fluid =

= S.G x ρ_{water}

= 62.30 x 1.25

= 77.88 lbm/ft³

Density of the fluid is equal to 77.88 lbm/ft³

The person selling the bananas in the market says that they have a 'weight' of 1 kg. Explain what is

Bas_tet [7]

In physics weight is the force exerted on a body by gravity so, the seller should have said it has a mass of 1 kg because mass is the amount of matter in an object.
