Current that is passing through the coil (I), The magnetic field that is created due to passing current (B). Mass = 3 kg Are you sure that you use enough? The force has to be perpendicular to the lever arm, which is the line that connects the pivot point and the point at which we apply the force. Direct link to Halomoan's post What's the idea behind mo, Posted 6 years ago. Direct link to levgenid's post Although it is not exactl, Posted 7 years ago. Furthermore, a force applied at the pivot point will cause no torque since the moment arm would be zero (\(r = 0\)). L = I Where: Further, if you are familiar with determinants, \(A \times B\), is, \(A \times B = \Biggr| \begin {matrix} i \quad j \quad k \\ A_x \; A_y \; A_z \\ B_x \; B_y \; B_z \end{matrix} \Biggr|\), Comparing Figures CP1 and CP2, we notice that Moment of inertia = 2 kg m Torque Calculator. We begin by substituting our result from Equation (17.3.14) into Equation (17.4.14) for the infinitesimal rotational work, \[d W_{\text {rot }}=I_{S} \alpha_{z} d \theta \nonumber \]. That gives us a shorter torque formula of =rF\tau = r\times F=rF, since sin(90)=1\sin(90\degree) = 1sin(90)=1. Other Inquiries:physinfo@uoguelph.ca, Department of Physics, Main Office So you can also enter a known torque value and either the lever arm distance or the force to find the missing force or lever arm distance, respectively. The force you used was, \(\tau = r \times F = r F \sin (\theta)\), Note that this is only the magnitude of the torque; to complete the answer, we need to find the direction of torque.
