1. The problem statement, all variables and given/known data B. Torque Due to Perpendicular Component of F 4. The tension in string 1 (on the left) is not known, so we will calculate the torques about this point (10.0 cm). (That way, there is no torque due to the unknown string 1.) Calculate the torque due to the weight of the meter stick about 10.0 cm. 5. Calculate the perpendicular component of the tension in string two (T2sinθ) for the five different values of θ. Is the perpendicular component of the tension the same for each trial? Calculate the torques due to string 2 about x = 10.0 cm. Is the net torque acting on the meterstick about 10.0 cm equal to zero for each trial? Mass of meter stick= 149g Clamps(these are the things that connect the string to the meter stick) = 17g right side weight = 200g left side clamp at 10.0cm Center of mass of ruler = 50cm right side clamp at 90 cm 2. Relevant equations t= fl = rfsin([itex]\theta[/itex]) = Ftanr 3. The attempt at a solution Calculate the torque due to the weight of the meter stick about 10.0 cm. 4. The center of mass of the meter stick was 50 cm So the only thing that is torquing it is the gravity of the meter stick, from the 10cm point The weight of the meter stick(including 2 clamps = 1.79N t= rfsin(90) [itex]\ t= (.40m) (1.792 N) (sin(90)) [/itex] [itex]\ t= .717NM [/itex] Negative 717NM since the torque is clockwise Can someone confirm that I am doing this correctly? 5. Im just going to do the calculations for trail 1 to see if i am doing it correct Calculate perpendicular component of tension in string 2 [itex]\ t2sin = opposite [/itex] [itex]\ (1.98N) sin 31 = 1.02 N [/itex] Calculate the torques due to string 2 about x = 10.0 cm. t= Ftanr [itex]\ t= (1.02 N) (.80 m)[/itex] [itex]\ t= .816 NM [/itex] Positive since torque is counterclockwise. Calculate the torque due to the weight of the meter stick about 10.0 cm. For this step i just added the string 2 torque from the torque measured in 4. net torque = .-717NM + .816NM = .099 Can someone check if i did this correctly?
