Chapter 13, Problem 37P

The 19-Mg truck hauls the 40-Mg trailer. If the unit starts from rest on a level road with a tractive force of 23 kN between the driving wheels of the truck and the road, compute the tension T in the horizontal drawbar and the acceleration a of the rig.

The 16-Mg truck hauls the 37-Mg trailer. If the unit starts from rest on a level road with a tractive force of 21 kN between the driving wheels of the truck and the road, compute the tension T in the horizontal drawbar and the acceleration a of the rig. Answers: T = a = i 37 Mg KN m/s² 16 Mg

The 1.8-kg slider fits loosely in the smooth slot of the disk, which rotates about a vertical axis through point O. The slider is free to move slightly along the slot before one of the wires becomes taut. If the disk starts from rest at time t = 0 and has a constant clockwise angular acceleration of 0.48 rad/s², plot the tensions in wires 1 and 2 and the magnitude N of the force normal to the slot as functions of time t for the interval Ost≤4.1s. After you have made the plots, answer the questions. Questions: When t = 0.6 S: When t = 3.3 S: T₁ = i T₁= i 120 mm N.T2= N.T2= i N.N= N,N= i i N N
