In a machine shop, a hydraulic lift is used to raise heavy equipment for repairs. The system has a small piston with a cross-sec
Mrac [35]

Answer:

F_s=1075.9493\ N

Explanation:

Given:

  • area of piston on the smaller side of hydraulic lift, a_s=0.075\ m^2
  • area of piston on the larger side of hydraulic lift, a_l=0.237\ m^2
  • Weight of the engine on the larger side, W_l=3400\ N

Now, using Pascal's law which state that the pressure change in at any point in a confined continuum of an incompressible fluid is transmitted throughout the fluid at its each point.

P_s=P_l

\frac{F_s}{a_s}=\frac{W_l}{a_l}

\frac{F_s}{0.075} =\frac{3400}{0.237}

F_s=1075.9493\ N is the required effort force.

A car travels from Bangalore to Mumbai and returns back on 20 hrs. What is the average velocity and average speed of the car if
irinina [24]

Answer:

Explanation:

Average speed= Total distance/ Total time

                        

Initial reading= 2200

final reading= 3800

total distance= Final reading -initial reading  = 3800-2200 = 1600 km

total time= 20 hrs

Average speed= 1600/20

                        = 80 km/hr

CONVERTING km/hr TO m/s  

To convert km/hr to m/s just multiply

Recall that,

1000m = 1 km

60 secs = 1 min

60 mins = 1 hr

( 80 × 1000 ) meters / ( 60×60 ) secs

80000m / 3600s

= 22.22m/s
