A CAT 834H four-wheel tractor (rubber tires, high pressure), with an operating weight of 108,180 lb , is pulled up a road whose slope is + 3 .0% at a uniform speed. If the average tension in the towing cable is 6,060 lb, what is the rolling resistance of the road? Hint: The useable power for overcoming rolling resistance is equal to the tension in the towing table but some of it will be consumed on overcoming grade resistance By...

The tractor has a weight of
4500 lb with center of gravity at G. The driving traction is
developed at the rear wheels B, while the front wheels at A are
free to roll. If the coefficient of static friction between the
wheels at B and the ground is s = 0.5 possible to pull at P = 1200
lb without wheels at B to slip or the front wheels the ground.

The 605,000-lb jet airliner has a touchdown velocity v = 141 mi/hr directed θ 0.670 below the horizontal. The touchdown process of the eight main wheels takes 0.78 sec to complete. Treat the aircraft as a particle and estimate the average normal reaction force at each wheel during this 0.78-sec process, during which tires deflect, struts compress, etc. Assume that the aircraft lift equals the aircraft weight during the touchdown 00000O oo00 ooo Answer: Nave - lb

Since 1967, Tractor Pull
competitors from around the country have met at the Wood County
Fairgrounds
in Bowling Green, Ohio, for the National Tractor Pulling
Championship (www.pulltown.com). The tractor
or truck attempts to pull a heavy weight (called the
“sled”) as far as possible, up to the length of the track
(320 feet).

The Goodtread Rubber Company has the following two divisions. (i) Tire Division -- which manufactures tires for new autos (ii) Recap Division -- which manufactures recapping materials that are sold to independent recapping shops. Since auto manufacturing moves up and down with the general economy, the Tire Division's earnings contribution to Goodtread's stock price is highly correlated with the returns on most other stocks. If the Tire Division was operated as a separate company the beta of its assets would...
