A rope tied to the box runs vertically upward over a pulley and a weight is hung from Determine the force that the table exerts on the box if the weight hanging on the other side of the i palley weighs each of the following )36 N b) 60 N c 105 N aro-eak n at S knch and then a deer.

E) St cannot be determined from the information given because wa ust atso know directions traveied

Explanation / Answer

a)

Force of the weight of box= 74 N

Force due to counter weight = 36 N

The force due to counter weight is transmitted through as tension on box= 36 N

Net downward force on box = 38N

So force of reaction from table on the box = 38N

b) force of counter weight = 66N

Tension in string = 66 N

Net downward force on box =74 N - 66 N = 8N

Reaction of table on Box = 8N

c) Force of counterweigght = 105N

Tension in string = 105N

Net force on box( is upwards) =105N-74 N = 31N

So force of table on box = 0 N
