Answer to Question #73968 in Mechanics | Relativity for malelelo mishumo
A meter stick of negligible mass is fixed horizonally at its 100 cm mark.imagine this meter stick used as a displayfor some fruits and vegetables with record-breaking masses.a lemon with mass of 3.9kg hangs from the 70cm mark and a cucumber with a mass of 9.1kg hangs from the xcm mark .what is the value of x if the net torque acting on the meter stick is 56N in the counter clockwise direction.
Given. l_0=100 cm=1 m; l_1=70 cm=0.7 m; m_1=3.9 kg; m_2=9.1 kg; τ_net=56 N∙m. Find. l_2-? Solution. So, τ_net=τ_1+τ_2=F_1∙d_1+F_2∙d_2=m_1 g(l_0-l_1 )+m_2 g(l_0-l_2 )→
