Help me solve this
The physics associated with statics has considerable applications in engineering. As a mechanical engineer working for a tow
truck manufacturer, you have been asked to evaluate the purchase of a new line of towing cable. The supplier claims that,
although its cables are not as strong as its competitors maximum tension capability of lb the cost savings make it a
good investment.
A schematic of the towing configuration is shown.
The car weighs lb which is as large as the
company expects their tow trucks to service. The
overall length L of the car is ft and the
distance d between the midpoints of the front and
back tires is ft The bottom of the car's frame
is a height hf above the ground, and the
car's center of mass is a height hCM above
the bottom of the car's frame. The angle phi
between the midpoint of the tires and the tow cable is @
Assume the CM of the car is positioned exactly halfway across its length, the geometry of the wheels and frontrear of the car is
symmetrical, and that the coefficient of friction between the road and tires is sufficient to maintain no acceleration in the system.
Calculate the tension T in the cable just as the front of the car
begins to lift off the ground.
Assume that the front end rises at a constant velocity.
