Hydraulic brakes and hydraulic lifts operate on:
RRB RPF Constable
03/03/2025 / Shift III
2025
✓ Answer:CPascal's law
An applied pressure is transmitted throughout the confined liquid, allowing force transmission and multiplication.
22
A tank partly filled with liquid accelerates uniformly horizontally. What happens to the liquid surface when acceleration is in the direction of motion?
RRB NTPC (Stage-I)
17/01/2017 / Shift I
2017
✓ Answer:AIt falls at the front and rises at the back
In the accelerating tank frame, effective gravity has a backward component. The free surface rises at the back and falls at the front.
23
The increase in a ship's speed is based on:
RRB NTPC (Stage-I)
22/04/2016 / Shift II
2016
✓ Answer:AArchimedes' principle
Source key: A, but the wording is erroneous. Archimedes' principle explains flotation. An increase in speed due to a net propulsive force is described by Newton's second law, option D.
24
Who first devised a method of measuring atmospheric pressure?
RRB RPF SI
12/12/2024 / Shift III
2024
✓ Answer:DTorricelli
Evangelista Torricelli developed the mercury barometer for measuring atmospheric pressure.
25
What is an ideal fluid?
RRB SSE
21/12/2014
2014
✓ Answer:DFrictionless and incompressible
An ideal fluid is taken to have zero viscosity and constant density.
26
What is the upward force exerted by a fluid on an immersed object called?
RRB NTPC (Stage-I)
18/04/2016 / Shift III
2016
✓ Answer:ABuoyant force
The upward resultant of fluid pressure forces is buoyant force or upthrust. The source uses 'pressure' where it means force.
27
What is the relation between thrust T, pressure P and area A?
RRB ALP (Stage-I)
26/11/2024 / Shift III
2024
✓ Answer:AT = P × A
Pressure is thrust per unit area, P = T/A, so T = PA.
28
Water strikes a wall normally at 10 m/s with a volume flow rate of 0.0001 m³/s. What force does it exert if its normal velocity becomes zero?
RRB Group-D
31/10/2018 / Shift III
2018
✓ Answer:A1 N
F = ρQv = 1000 × 0.0001 × 10 = 1 N, using water density 1000 kg/m³. This follows from momentum flow; the source incorrectly introduces gravitational acceleration.
29
What is another name for the upward force exerted by water on a submerged body?
