Question

Hi! I'm working on a torque worksheet, but I'm stuck on a question. I don't know how to answer this little table!

14. The equations of equilibrium (St 30, F 300 are applied to two different examples shown below. Fill in the table that follows using the information in the equations. In this problem, Nstands for normal force and N for Newton, the unit offorce a. Equations 1.0N -2.0 +N Draw an extended-body ne the unknown Determi force diagram consistent quantities in the with the equations. equations. Sketch the situation. Describe a possible situation in words. Ti(1.0 m)sin 37 6N)(1.0 b. Equations x equation: cos 6 Ticos 37° 0 y equation: Fie sin 6 2N 6N T sin 37 0 Draw a force diagram Determine the consistent with the unknown quantities in the equations. sketch the situation. Describe a possible situation in words.

Explanation / Answer

a) 2*0.25+N*0+1.0*0- T2*0.40=0

0.5-T2 0.40=0

T2=0.5/0.40 = 1.25 N

-2.0+N-1.0-T2=0

-2.0+N-1.0-1.25=0

N=4.25 newtons

b) 0-1-6+T1*0.6=0

T1=11.67 N

F cos theta- 11.67*0.7986=0

F costheta=9.32 ,

Fsintheta= 8-11.67*0.60 = 0.9768

F= Sqrt(9.32^2 + 0.9768^2) = 9.37 N

Theta= tan inverse(0.9768/9.32) = 5.98 degrees

I have done the unkown quantities in each equations , Now you can describe the situation and draw that accordingly. While drwaing remember negative tourque is clockwise, Positive tourque is anticlockwise. For forces up is positive,own is ngative. Righ is positive left is negative.

And whenver you see in case of touque timesd wuth zero that means that force is at the pivot or passing through the pivot.
