position in x direction is given as
a = 1.30
b = 1.45
now average velocity in x direction is given as
Now similarly in Y direction position is given as
here
c = 0.129
d = 1.16
now by the average speed formula
Explanation and answer:
This problem is best answered by drawing a figure as a first step.
ABC is the scaffold.
A downward force of 500N is applied downwards at 1m from end A.
The weight of 800N is exerted by the scaffold uniformly distributed between A & C.
At A and C, ropes are attached to support the load.
Let Fc=tension in rope passing through C.
Take moments about A:
Fc = (500N * 1m +800N*(3+1)/2m / 4m
= (500 Nm + 1600Nm) / 4m
= 2100 Nm / 4m
= 525 N
The pumps which supplies energy to move the water from the ground to a high elevation. The charges that flow throughout the wires.
