Question
What is the solution to get the answer for the highlighted (yellow) equation
Transcribed Image Text:Given
The angle of enclined surface with Horizontal (0) = 25°
Applied force (P)
Static coff of friction (Mg) = 0.35
Kinetic coff of friction (UK) = 0.25
.
= 750N
Transcribed Image Text:S
FB-D
Now,
1200 N
Now
Balancing Horizontal force
Balancing force perpendicular to Inclined plane.
(Vertical Force)
N Co 25° + f sin 25° = 1260 N
(0.91) N + (0.42) F = 1260 N
By solving and
IN
750 N+FOD 25° = Nsin 25°
750 N + 0.91
= 0.42 N
F = -177-7 N
N = 1400-69 N
Static friction force.
:: F <F₂ }
-0
F₁ = μg N
-
= 0.35 x 1450.69 N
= 490.24 N
N = Normal force
F = friction force.
