2.22. Holding a cone * With two fingers, you hold an ice cream cone motionless upside down, as shown in Fig. 2.28. The mass of the cone is m, and the coefficient of static friction between your fingers and the cone is u. When viewed from the side, the angle of the tip is 20. What is the minimum normal force you must apply with each finger in order to hold up the cone? In terms of 0, what is the minimum value of u that allows you to hold up the cone? Assume that you can supply as large a normal force as needed. 2.23. Keeping a book up ** The toals of R. finger finger
