729 If T 600N CD 1000 N and T 500N calculate the moment that

7.29 If T 600N, CD 1,000 N, and T 500N, calculate the moment that each one AE exerts about the point O. 1.5 m 1.5 m 3 m

Solution

moment about point O by for TAE = TAE *Sin 30 * 3

= 600*0.5*3

= 900Nm

moment about point O by for TCD = TCD *Sin 41.8 * 3

=1000* .667*3

=2000 Nm

moment about point O by for TGF = TGF Sin* 41.8 * 1

= 500*.667*1

=333.5 Nm
