A 13,000-N vehicle is to be lifted by a 25-cm diameter hydraulic piston. What force needs to be applied to a 5.0 cm diameter pis
MaRussiya [10]

Answer:

Explanation:

We shall apply Pascal's Law in fluid mechanics

According to it , pressure is transmitted in liquid from one point to another without any change .

25 cm diameter = 12.5 x 10⁻² m radius

Area = 3.14 x (12.5 x 10⁻²)²

= 490.625 x 10⁻⁴ m²

Pressure by vehicle

Force / area

13000 / 490.625 x 10⁻⁴

= 26.497 x 10⁴ Pa

5 cm diameter = 2.5 x 10⁻² radius

area = 3.14 x (2.5 x 10⁻²)²

= 19.625 x 10⁻⁴ m²

If we assume required force F on this area

Pressure = F / 19.625 x 10⁻⁴ Pa

According to Pascal Law

F / 19.625 x 10⁻⁴  = 26.497 x 10⁴

F = 19.625 x 26.497

= 520 N

Help me answer these, please. I GIVE CROWNS!! PLEASE!!
bija089 [108]

Answer: 1- A diagram showing the forces acting on the object.

2- The force vector describes a specific amount of force and its direction. You need both value and direction to have a vector.

3- A vector quantity has a direction and a magnitude, while a scalar has only a magnitude. You can tell if a quantity is a vector by whether or not it has a direction associated with it.

4- I don’t know

5- When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces

6- By applying an unbalanced force, you can change the motion of an object. Unbalanced forces can make an object at rest start moving, make a moving object stop, or change the direction and speed of the object.

7- If the forces on an object are unbalanced, this is what happens: a stationary object starts to move in the direction of the resultant force.

8- Imbalance or unequal force

9- The result is no motion. Balanced forces can cancel each other out. Any time there is a balanced force, the object does not move.

10- net force is the vector sum of all the forces that act upon an object.

When a box of chocolate bars is in mechanical equilibrium, what can be correctly said about all the forces that act on it?
rjkz [21]

Answer:

All the forces are opposite and equal and will give net force zero.

Explanation:

Mechanical equilibrium is the equilibrium in which the total force on the system is zero means the system is neither accelerated nor any kind of torque on the system.

The mechanical system can also be defined as the equal forces are applied in opposite direction in a system which cancels out all the forces, will give net force zero.

Therefore, when a box of chocolate bars is in mechanical equilibrium all the forces in this system  are equal and the opposite which balances each other will give net force zero.
