Suppose you need to remove a nail from a board by using a claw hammer. What is the input distance for a claw hammer if the output distance is 1.8 cm and the mechanical advantage is 5.4?

input:33

Step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
