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
![T = \frac{1}{9}[m_sg(1.9\:\text{m}) + m_pg(4.2\:\text{m})]](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B1%7D%7B9%7D%5Bm_sg%281.9%5C%3A%5Ctext%7Bm%7D%29%20%2B%20m_pg%284.2%5C%3A%5Ctext%7Bm%7D%29%5D)
To solve for the the mass of the equipment , use the value for T into Eqn(1):
To solve this problem you must know the following information:
1. Two lines are parallel when they are equidistant and never intersect each other, therefore, the have equal slope.
2. A transversal line is a line that cut two or more lines at different points.
3. Based on the information shown above, you have that the 30-yard line and the goal line are equidistant, they do not intersect each other and both have the same slope. Therefore, they are parallel.
4. The straight line with an angle intersect the parallel lines, therefore, it is the transversal.
The answer is: The 30-yard line and the goal line are parallel. The straight line that shows the path of the football player is the transversal line.
Answer:
ok ill be your friend ok dont worry
Answer:
27
Step-by-step explanation:
Multiply 8×.75 (6)
Add that to 21
Answer:
2.2 inches
Step-by-step explanation:
This is because of the stated scale rate. 1/5 is equal to 20% with that 20% of 11 inches would yield 2.2 inches hope this helps :)
