Question

Выкладываю третий раз помогите пжжж Малый поршень гидравлического пресса опустился на 25 см под действием силы 650 Н. Площадь малого поршня равна 3 см², а площадь большого — 15 см² Какая сила приложена на большой поршень и на какую высоту он переместился. Сила, приложенная к большому поршню, равна__H Большой поршень переместился на__см​

Answer 1

Ответ: 3250Н; 5см

Объяснение:

Дано:

h1=25cм

F1=650Н

S1=3cм²

S2=15cм²

----------------

F2-?; h2-?

F1/S1=F2/S2

F2=F1*S2/S1=650*15/3=3250Н

S1*h1=S2*h2

h2=S1*h1/S2=3*25/15=5см

Answer 2

Calculation of Force and Displacement

To calculate the force applied to the large piston and the displacement it undergoes, we can use Pascal's law, which states that the pressure exerted on a fluid in a closed system is transmitted equally in all directions. In this case, the fluid is the hydraulic fluid in the press.

The formula to calculate the force exerted on the large piston is:

Force on large piston = Force on small piston × (Area of large piston / Area of small piston)

Given: - Force on small piston = 650 N - Area of small piston = 3 cm² - Area of large piston = 15 cm²

Let's calculate the force on the large piston:

Force on large piston = 650 N × (15 cm² / 3 cm²)

To calculate the displacement of the large piston, we can use the principle of conservation of volume. The volume of the fluid displaced by the small piston is equal to the volume of the fluid displaced by the large piston.

The formula to calculate the displacement of the large piston is:

Displacement of large piston = (Area of small piston × Initial height of small piston) / Area of large piston

Given: - Initial height of small piston = 25 cm - Area of small piston = 3 cm² - Area of large piston = 15 cm²

Let's calculate the displacement of the large piston:

Displacement of large piston = (3 cm² × 25 cm) / 15 cm²

Now, let's calculate the values:

Force on large piston = 650 N × (15 cm² / 3 cm²) = 3250 N

Displacement of large piston = (3 cm² × 25 cm) / 15 cm² = 5 cm

Therefore, the force applied to the large piston is 3250 N, and it moves a distance of 5 cm.

Please note that the above calculations are based on the given information and assumptions about the hydraulic press system.
