BASIC TPOST DO NOT ASSIST DO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST This assignment focuses on long metal rod pivoted about a frictionless axis and set rotating from rest by a single torque. DO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASS center O NOT POST DO NOT ASSIST Fp DO NOT POST DO NOT ASS ........... O NOT POST DO NOT ASSIST DO NOT POST DO NOT ASS O NOT POST DO NOT ASSIST ... DO NOT POST DO NOT ASS axis O NOT POST DO NOT ASSIST L DO NOT POST DO NOT ASSIST DO NUI PUSI DO NUI ASSIST DO NOT POST DO NOT ASSIST(1) MVQ The rod's length is L, its mass is M, and the axis is a distance d from its center. Both d and the rod's rotational inertia / about this axis depend on the last two digits of your phone number:POST DO NOT ASSIST DO 00-32: d = L/6, I=_ML2 33-65: d = L/4 , I= 48 LZ ML? DO 66-99: d = L13, I= -ML 36 POST Just state your version here. ASSIST DO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST (2) RNG Choose and list L (2-5 m) and M (10-30 kg), then calculate your rod's rotational inertia / about your assigned axis.ST DO NOT ASSIST DO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST (3) RNG A mechanical arm begins exerting a constant push Fp (20-40 N) on the far end of the rod from the axis, directed at an angle 0 (40-609) from the length of the rod (see diagram). List your randoms, then calculate the torque about this axis caused by FpDO NOT POST DO NOT ASSIST DO NOT POST DO NOT ASSIST (4) Calculate the rod's angular acceleration about the axis caused by this torque. NOT POST DO NOT ASSIST (5) RNG This angular acceleration remains constant while the rod speeds up from rest, after which the arm ST disengages and the rod spins freely at a constant angular velocity. The rod completes 10-30 rev (2 SF: whole numbers only!) while speeding up. Calculate the time this takes and the rod's final angular velocity. ASSIST (6) Now, while the rod is spinning at its final angular velocity, which end of the rod (left or right) has the greater translational speed? Explain in 1-2 sentences. POST DO NOT ASSIST DO NOT POST DO NOT ASSIST (7) Calculate the translational speeds Vleft Vright of each end of the rod. SIST DO NOT POST DO NOT ASSIST
