Chapter 5, Problem 32SP

A 900-N lawn roller is to be pulled over a 5.0-cm high curb (see Fig. 5-22). The radius of the roller is 25 cm. What minimum pulling force is needed if the angle θ made by the handle is (a) 0° and (b) 30°? [Hint: Find the force needed to keep the roller balanced against the edge of the curb, just clear of the ground.]

6-63 The wrecker truck of Fig. P6-63 has a weight of 15,000 lb and a center of gravity at G. The force exerted on the rear (drive) wheels by the ground consists of both a normal component By and a tangential component B, while the force exerted on the front wheel consists of a normal force Ay only. Determine the maximum pull P the wrecker can exert when e- 30° if B, cannot exceed 0.8B, (because of friction considerations) and the wrecker does not tip over backward (the front wheels remain in contact with the ground). 9. 10 ft 4 ft 6.5 ft - 8 ft+5 ft

A cubic crate of side s= 2.0 m is top-heavy: its CG is 18 cm above its true center. How steep an incline can the crate rest on without tipping over? [Hint: The normal force would act at the lowest corner.]
