Problem 8.20

Solve 8.19 assuming that the coefficients of friction at B are zero. PROBLEM 8.19 Wire is being drawn at a constant rate from a spool by applying a vertical force P to the wire as shown. The spool and the wire wrapped on the spool have a combined weight of 20 lb. Knowing that the coefficients of friction at both A and B are s = 0.40 and k = 0.30, determine the required magnitude of the force P.

ENGR 121 B Lab Notes for 10/19/2016 Spencer Kociba ● If/else statements ○ if() ■ Operation where if what is in () is true, it will carry out the action given right after the condition on the next line ○ elseif() ■ Only executes if 1st condition is false; will check a second condition ○ else() ■ If the “if()” and “elseif()” statements are false, follow the commands after this ○ Progression: ■ if() ■ elseif() ■ elseif() ■ …. ■ else() ○ **stops progressing as soon as a condition is satisfied ○ Nesting ■ if()
