mechanics doubt
« on: February 26, 2010, 11:38:21 am »
An electric light mass mkg in a workshop is held over a particular place by two strings attached to the light bulb holder.
this is modelled by a particle suspended by two straight strings inclined at angles 60 and 65 above the horizontal.
find the tension in the strings.
where m = 0.5
everyday we wake up is a miracle, then how do we say miracles dont happen?????

T1cos60=T2cos65

T1sin60+T2sin65=0.5g

solve simultaneously to get T1 and T2
