Answer:
- 256 lbs
Explanation:
The internal axial load at point D can be calculated as the change in the subjected loads. if the magnitude of the horizontal direction = zero
; Then:
internal axial load at point D = Δ P
= -(P₂ - P₁)
= - ( 888 lbs - 632 lbs)
= - 256 lbs
Answer:
It should be mentioned that an efficient way to work this vector addition problem is with the cosine law for general triangles (and since
a
,
b
and
r
from an isosecles triangle, the angles are easy to figure). However, in the interest of reinforcing the usual systematic approach to vector addition, we note that the angle
b
makes with the +x axis is 30
0
+105
0
=135
0
(a) The x component of
r
x
=(10.0m)cos30
0
+(10.0m)cos135
0
=1.59m
(b) the y component of
r
is r
y
=(10.0m)sin135
0
= 12.1 m.
(c) the magnitude of
r
is r = ∣
r
∣=
(1.59m)
2
+(12.1m)
2
=12.2m
(d) The angle between
r
and the +x direction is tan
−1
[(12.1m)/(1.59m)]=82.5
0

Answer:
The correct answer is - radiant.
Explanation:
Electromagnetic waves are the transverse waves that get energy as radiation from the source and transfer to an absorber so, the radiant energy is the energy of electromagnetic waves.
Electromagnetic waves are can travel in space unlike mechanical waves and are made up of photons, tiny packets of energy. Electromagnetic waves or spectra include radio waves, infrared, light, microwaves, UV, X-rays, and gamma rays.
Answer:
longitudinal wave
