Problem 9: When using a pencil
eraser, you exert a downward force of 4.5 N at a distance
of 2.3 cm from the hardwood-eraser joint. The pencil has a
2.4 mm radius and is held at an angle of 19° to
the horizontal. The shear modulus of wood is 1.00 × 1010
N/m2 and the strain modulus is 1.50 × 1010
N/m2.

The words “Block on verge of slipping” should appear. This means
that the static frictional force on the aluminum block has reached
its physical upper limit. It is not possible, given the
intermolecular forces between the atoms in the welds, for the
static frictional force to be any larger. We shall label this
maximum static frictional force as
f→s,max. What is f→s,max on the block...
