Homework Statement
A brick weighs 15.0 N and is resting on the ground. Its dimensions are 0.203 m 0.0890 m 0.0570 m. A number of the bricks are then stacked on top of this one. What is the smallest number of whole bricks (including the one on the ground) that could be used, so that their...
Find the equation of the line normal to the curve at (0,0). (Normal lines are perpendicular to the tangent lines)
2y + sinx = xcoxy
I found the derivative to be (cosy - cosx)/ (2+ xsiny)
then the slope tangent is 0...then the slope perpendicular to it is undefined...so then is the...
Find the equation of the line tangent to the curve at (5, -3)
(x-2)^2 + (y+3)^2 = 9
I solved the derivative to be dy/dx = ((-2x+4)/ (2y+6))
when i plugged in the points (5, -3) I got the slope as -6/0...How is this possible??
How can i find the equation of this curve if the slope is...
can you explain to me what the website did that i didnt..cause i need to know how to do this for a test
Correct Ans:
29072.0130875 N for tension
Sum of forces =
26682.98896
ETorque = 0
Fl(D) + Wb (.5 D) - Ty(D) = 0
12.0E3N(4.60 m) + 4.50E3N(2.75) - Ty(6.069m) = 0
i used it here.....^ the T is for the cable that's added to the beam
A uniform steel beam of length 5.50 m has a weight of 4.50 103 N. One end of the beam is bolted to a vertical wall. The beam is held in a horizontal position by a cable attached between the other end of the beam and a point on the wall. The cable makes an angle of 25.0° above the horizontal. A...
