Answer:
it is the dependent since it keeps changing over time get it :)
Explanation:
Answer:
<em>1.11m</em>
Explanation:
From the diagram we are given the following forces;
F1 = 24.3N
F3 = 30N
Since the sum of upward forces is equal to that of downward force, then;
F2 = F1 + F3
F2 = 24.3N + 30N
F2 = 54.3N
Required
Distance between B and C
First we need to get Length of AC
Take moment about A
Anticlockwise moment = F3 cos20 * AC
Anticlockwise moment = 30ACcos 20
Clockwise moment = 1.2 * F2
Clockwise moment = 1.2(54.3) = 65.16Nm
Applying the principle of moment;
Sum of ACW moment = Sum of CW moments
30ACcos 20 = 65.16
AC = 65.16/30cos20
AC = 65.16/28.19
AC = 2.31m
Get the distance BC
AC = AB + BC
BC = AC-AB
BC = 2.31 - 1.2
BC = 1.11m
Hence the separation between B and C is 1.11m
<em>Note that the force F1 got in (a) was the value used in the calculation.</em>

The correct answer is B.g/mL
Figure A shows cross section of a land form or rock. In Figure B, compression stress is applied on it. When compression stresses are applied on a rock, it squeezes the rock cause fold or fracture. The fault formed by compression stress is called thrust fault. If the compression stresses/ force continue to act on a rock it will converge and form thrust fault. In Figure C, tension stresses is applied on the rock. When a tension stress applied on a rock it deforms/ lengthen. There are three type of deformations occur due to tension stresses. One is elastic deformation, in which, rock retains it original shape when force/stresses are removed. Second is plastic deformation, in which rock lengthen and change occur permanently. Third type of deformation is result into fracture or breaking of rock. In Figure C, shear stresses are applied on rock. Shear stresses are applied with equal magnitude but in opposite direction. It cause breaking of rock.
