СРОЧНОООООПОМОГИТЕ РЕШИТЬ!!УМОЛЯЮМалый поршень гидравлического пресса площадью S1 = 10 см2 под действием силы F =400 Н опустился на h = 16 см. Определите вес груза, поднятого большим поршнем, если площадь большого поршня S2 = 80 см2. На какую высоту поднялся большой поршень?ОТВЕТЫ: Р=3.2kH h=2.0 см

Answer 1

P=mg/s=P/s
P1/s1=P2/s2
P2=P1s2/s1
P2=400*80/10=3200H
H1*P1=H2*P2
H2=H1P1/P2
H2=16*400/3200=2см

Answer 2

Calculation of Weight Lifted and Height Raised in a Hydraulic Press

To solve this problem, we need to use the principles of Pascal's law, which states that pressure is transmitted equally in all directions in an enclosed fluid. In a hydraulic press, a small piston exerts a force on a small area, which is transmitted to a larger piston with a larger area. This allows for the amplification of force.

Let's calculate the weight lifted by the larger piston and the height it is raised.

Given: - Area of the small piston (S1) = 10 cm^2 - Force applied on the small piston (F) = 400 N - Height the small piston is lowered (h) = 16 cm - Area of the large piston (S2) = 80 cm^2

To find the weight lifted by the larger piston, we can use the formula:

Weight lifted = Force applied on the small piston * (Area of the large piston / Area of the small piston)

Substituting the given values into the formula:

Weight lifted = 400 N * (80 cm^2 / 10 cm^2)

Weight lifted = 400 N * 8

Weight lifted = 3200 N

Therefore, the weight lifted by the larger piston is 3200 N.

To find the height the larger piston is raised, we can use the formula:

Height raised = (Force applied on the small piston * height the small piston is lowered) / (Area of the large piston)

Substituting the given values into the formula:

Height raised = (400 N * 16 cm) / 80 cm^2

Height raised = 6400 N cm / 80 cm^2

Height raised = 80 cm

Therefore, the height the larger piston is raised is 80 cm.
