Packet C: Tossup 13

One of these quantities is divided by the flexural rigidity in the integrand of a theorem developed by Mohr. The signs of these quantities determine whether a structure undergoes “hogging” or “sagging.” One (10[1])of these quantities is defined as a resultant internal (-5[1])couple and is typically plotted alongside shear in a structural (-5[1])design (10[1])setup. (-5[2])These quantities (10[1])are defined as the product of another quantity (10[1])and some power of distance and include (10[1])a “bending” type. (10[4])Another of these (10[2])quantities, (10[2])which defines a rank-2 (10[2])tensor (10[1])appearing (10[1])in the Euler equations, (10[2])is invariant along (-5[1])an axis under (-5[2])the “stretch rule.” (10[2])For 10 points, (-5[1])name these quantities (10[1]-5[1])that describe the distribution of another quantity relative (10[1])to a fixed reference point, such (10[1])as (-5[1])the analogue of mass (10[3]-5[1])in rotational (10[1])dynamics (10[2])called (10[1])one (10[2]-5[1])“of inertia.” (10[6])■END■ (10[18]0[1])
