Hence the expression is dimensionally consistent and contains no obvious algebraic errors 2. 3. We can “solve” certain physical problems with-out actually doing the detailed calculations needed for a complete solution. Thus, suppose we want an expression for the fre-
WebIn part (c) the parallel axis theorem is used and the rotational inertia of the rod and block are added, but the calculation for the block is incorrect so only 2 points were earned. In part … WebThe restoring torque is supplied by the shearing of the string or wire. Figure 15.22 A torsional pendulum consists of a rigid body suspended by a string or wire. The rigid body oscillates between θ=+Θ θ = + Θ and θ=−Θ θ = − Θ. The restoring torque can be modeled as being proportional to the angle: τ =−κθ. τ = − κ θ.
