Step-by-step explanation:
Let
= mass of the painter
= mass of the scaffold
= mass of the equipment
= tension in the cables
In order for this scaffold to remain in equilibrium, the net force and torque on it must be zero. The net force acting on the scaffold can be written as
Set this aside and let's look at the net torque on the scaffold. Assume the counterclockwise direction to be the positive direction for the rotation. The pivot point is chosen so that one of the unknown quantities is eliminated. Let's choose our pivot point to be the location of . The net torque on the scaffold is then
Solving for T,
or
To solve for the the mass of the equipment , use the value for T into Eqn(1):
Answer:
The probability that you will pull a banana on the first try and an apple on the second try = .024
Step-by-step explanation:
Given -
A refrigerator contains 50 pieces of fruit: 6 apples, 5 oranges, 10 bananas, 3 pears, 7 peaches, 11 plums, and 8 mangos .
Total no of fruit = 50
The probability that you will pull a banana on the first try and an apple on the second try =
=
= .024
