1. A uniform picture frame weighing 10N is supported. The cable on the right side makes an angle of 50 with the horizontal direction. Find the tension in the cords and the magnitude of the horizontal force F required to hold the frame in the position Homework Equations imagine a rectangular...

i think i got the answer but how come we go 100.6/0.3?

i don't get it :|

a thermometer reads -.3 degrees celsius at ice point and 100.6 degrees celsius at steam point. find the true temperature of a thermometer if thermometer read 18.2 degree celsius The Attempt at a Solution this is actually a simple math question that i need a little help with. i know what...

awsome, figured it out. i set x coord t1cosO - T3 and y coord as T1sinO + T2 - W(person+plank) set my t1 = 1/4(Wperson +2Mplank)/sinO then i just plugged in T1 to my other forumlas. thanks!

sorry the diagram didn't show up better there's a rope pointing left, one pointing up (on the left side) and one rope pointing tot he right at 40 degrees North east

Find the tension in each rope "torque" 1. A uniform plank of length 2m and mass 30kg is supported by three ropes. Find the tension in each rope when 700N person is 0.5m from the left end. 2. diagram ↑ / |...
