No. 22: The force of friction of a mower is 20 lb. What force must the man (in fig. 6-23 )exert along the handle to push it at constant speed ? Hint: look up example 6 in this section. You can get up to 10 points for answering correctky this discussion before monday's class.
Did i work...
Four forces each of magnitude 2750lb act at the same point. The angle between adjacent forces is 30degrees. find the resultant force. I worked it out and got FR= 0 in the x and 0 in the y is that right??
I have a problem where i have found the angle for one line but i can't find the angle for the other. See attached picture i couldn't find how to add the picture to the post without a url for it. so far i have the x and y values for two line I am only missing the third line.
f1 = 1570 lb ^x 0...
