Now give the object 4 wheels. The normal force between the 4 wheels and axles is the same (in total) 981 N, assume ü = 0.1, and say the wheel diameter is 1000 mm and axle diameter is 50 mm. So while the article still moves 10 m the sliding frictional surfaces only slide over each other a distance of 0.5 m. The work done is 981 visit site x 0.1 x 0.5 = 49 joules.

For front-to-back stability, the maximum height of an obstacle which an unarticulated wheeled vehicle can climb is a function of the wheelbase and the horizontal and vertical district of the center of concretion (CM). |
