Lnewqban reacted to Klystron's post in the thread RIP Jane Goodall (91), primatologist and conservationist with
Like.
I have a Jane Goodall anecdote that I think about often during these strange days. While visiting at Stanford University in Palo Alto... -

Lnewqban replied to the thread 2 wires attached to another wire attached to a block.Welcome! :cool: When your fingers are holding a suspended bad of groceries, do they feel increased or reduced weight of the...

Lnewqban reacted to haruspex's post in the thread 2 wires attached to another wire attached to a block with Like.
The other cords are not attached to the weight. Each body only "knows" about the forces that act directly on it. The suspended body is...

Lnewqban replied to the thread Why can I neglect angular momentum due to precession here?.Could you explain that idea a little more for me? How would you define precession in this case?

Lnewqban reacted to Baluncore's post in the thread Question about bonding ground and neutral with Like.
Fuses protect conductors from fault overcurrents, that might melt the insulation or the wires. The ground path is bonded to neutral...

Lnewqban reacted to hutchphd's post in the thread Question about bonding ground and neutral with Like.
The neutral current path offers a very low resistance path for the current, and so most of the power follows this path. The local...

Don't assume that EEs know much about this subject. It's a broad field and most don't ever deal with power distribution. Even if they...

Lnewqban replied to the thread Why can I neglect angular momentum due to precession here?.Welcome! I believe that you can neglect angular momentum due to precession here because the coin is rolling in balance of forces and...

Lnewqban reacted to haruspex's post in the thread I've come across another fluid pressure problem I don't understand with Like.
I do not understand the function of the check valve here. It is drawn as though allowing flow upwards, which means admitting air if the...

Lnewqban reacted to jbriggs444's post in the thread I've come across another fluid pressure problem I don't understand with Like.
I agree that the downward force (suction) from the water on the first piston (##F_1##) is 50000 N. I agree that the upward force...

Lnewqban replied to the thread I've come across another fluid pressure problem I don't understand.What is exactly what you don't understand? Both represented forces should be pointing in the opposite directions: both should be pulling...
