Question

SOLVED
5) A person pulls on a 50 kg desk w/ a 200N force acting at a 30° angle above the horizontal. The desk does not budge.
a) Write the equation that describes the forces which act in the x-direction.
b) Write the equation that describes the forces which act in the y-direction.
c) Determine the x and y components of the force of tension.
d) Determine the values of the frictional and normal forces.

6) Suppose the person were PUSHING down at a 30° angle with 200N of force. The desk still does not move.
a) Write the equation that describes the forces which act in the x-direction.
b) Write the equation that describes the forces which act in the y-direction.
c) Determine the values of the frictional and normal forces.

Answer 1

Show me your best guess.

Answer 2

@AllTehMaffs I'm assuming this is somewhat similar to the last problem?

Answer 3

I can help you understand, but if you only want answers then you're out of luck, keep begging that guy.

Answer 4

I'm not begging him, @Kainui. We went over a problem together and I'm asking him whether it works the same way for this one too.

Answer 5

yup yup, pretty much exactly like the last one ^_^

Answer 6

Gotcha.
But is there anything different about this (due to the fact that it's pulling & not pushing)?

Answer 7

what do *you think! ^_^

Answer 8

No?

Answer 9

correct! There's only the cosmetic difference of where the free body diagram arrows are drawn in the picture; there is no physical difference.

Answer 10

how about part a)

Answer 11

also, I'm a dumb and there is definitely a difference between this problem and the last - draw the free body diagram first

Answer 12

What o.o

Answer 13

one key difference - picture!

Answer 14

I don't have enough time to draw just tell me

Answer 15

:/ absurd



What's the normal force?
