The beam shown is made of a nylon for which the allowable stress is 24 MPa in tension and 31 MPa in compression. Determine the largest couple M that can be applied to the beam if d = 40 mm. 40 mm 15 mm 20 mm M The largest couple M that can be applied to the beam is N-m.

Help with this would be great, thanks!

Help!!! Please answer part A and part B correctly!!! Please!!!

A dust particle is suspended in the air (floating due to a small updraft and its own low mass) when a powerful loudspeaker plays a very low note (2 Hz so it can’t be heard but you can actually see the speaker move!). How will the dust particle move as a result of the speaker 
being turned on? Question 3 options:   A)  The dust particle will move up and down.   B)  The dust particle will be pushed across the room.   C)  The dust particle will move in a circular path.   D)  The dust particle will move side to side.

Mechanical engineering assistance. Please answer to the best of your ability. Show all work that is necesary.

can u solve the question using newton or lanrnage method in detail with hand written notes

Solve for me kindly EXPLANATION IT

I am confused because on my homework i got marked wrong for this, unless I used to many sig figs.
