Problem 39PE

using a pencil eraser, you exert a vertical force of 6.00 N at a distance of 2.00 cm from the hardwood-eraser joint. The pencil is 6.00 mm in diameter and is held at an angle of 20.0º to the horizontal. (a) By how much does the wood flex perpendicular to its length? (b) How much is it compressed lengthwise?

Step-by-Step Solution:

Step-by-step solution Step 1 of 6 The radius of the eraser is half of the diameter Step 2 of 6 The cross sectional area of the eraser is, Step 3 of 6 The perpendicular component of force acting to the eraser causes shear deformation The force exerted to the pencil 0 The pencil is held held at an angle of 20 with horizontal
