Q. An occupant of a car has a chance of surviving a crash if the deceleration all through the crash is not more than 30.00 g. Approximation the force on a 72 kg person decelerating at this rate.
Q. Estimate the deflection of the cylinder caused by the mass in the system. The mass causes a force of mg=50 kN. Evaluate results using oil and water as fluid. There is no free air in the fluid. The piston diameter is 150 mm and volumes: Vs=3.0 × 10-3 m3, Vl=0.60 × 10-3 m3, Vp=0.9 × 10-3 m3. The cylinder, hose and pipe are completely rigid Fluid properties Oil Water.
