azure arrow
#

show me ur working pls

#

let me send mine

south obsidian
azure arrow
#

Nws

south obsidian
#

That’s the short form

#

Wldnt r be 50gcos 30 + tsin20

#

Or is that wrong

drifting marsh
azure arrow
#

oh

#

is it what arjun said

drifting marsh
#

50gcos30 = R + Tsin20
R = 50gcos30 - Tsin20

#

Perpendicular equilibrium

south obsidian
#

Is it wrong?

drifting marsh
#

Brother is this supposed to be a 30

azure arrow
south obsidian
#

I will redo it

south obsidian
#

So u get that for vertical

#

What does it equal?

#

5a?

#

Or is it 5gsin 30=f+tcos20?

drifting marsh
#

Parallel eq
0.25(50gcos30 - Tsin20) + Tcos20 = 50gsin30

drifting marsh
#

Arjun you're actually not cooked at mechanics anymore

#

I'm proud

south obsidian
#

Haha thanks bro

#

The issue I had with this is I had that but I used chat gpt to check and then that gave me a weird answer but I went with the gpt one

drifting marsh
#

I see

south obsidian
#

T=162?

drifting marsh
#

,w 0.25(50(9.8)cos30deg - Tsin20deg) + Tcos20deg = 50(9.8)sin30deg

drifting marsh
#

Nice one

south obsidian
#

Painful,I put that but crossed it all out😭

#

What did u get for b?

drifting marsh
#

I didn't do it

south obsidian
#

R would be the same right? For part b as a

drifting marsh
#

R yes

#

Friction now acts in the opposite direction

south obsidian
#

Yes yes got that thanks bro

drifting marsh
#

👍

south obsidian
drifting marsh
#

Shouldn't it be + inside the bracket

#

Since they're both going down the slope

south obsidian
#

Idek why I put brackets in there thinking ab it

#

I added 50gsin30 to other side straight away

drifting marsh
#

Oh I didnt read the next line

#

You just completley ignored the brackets

south obsidian
#

Yeah idk why I put them now acc lol

drifting marsh
#

I can't read your working bro

south obsidian
#

What line

drifting marsh
#

All of it

#

How did you go from the one I screenshotted to the next

south obsidian
#

Add 50gsin 30 to other side

#

As a =5

#

250+245

drifting marsh
#

Oh I forgot you were given a mb 🤣

south obsidian
#

Ahha no worries

drifting marsh
#

I don't feel like checking the rest but it seems fine

#

Your method

south obsidian
#

#
