PHYS 101
Equilibria
If a force is exerted on an object, is it possible
for that object to move with constant velocity?
A hollow tube forms a
¾ circle. It is lying flat
on a table. A ball is shot
through the tube at
high speed. As the ball
emerges from the
other end, does it
follow path A, path B,
part C or path D?
The vectors below show five forces that can be
applied individually or in combinations to the
object. Which forces or combinations of forces
will cause the object to be in equilibrium?
What is the tension in the ropes?
The two angled ropes used to support the crate
can withstand a maximum tension of 1500 N
before they break. What is the largest mass the
ropes can support? Which rope will break first?
