2. Find the magnitude and direction of the resultant vector of two forces. The first force is 250 pounds at an angle of 25 degre
Lady bird [3.3K]

Answer:

Magnitude = 220.49pounds

Direction = 16.7°

Step-by-step explanation:

Find attached the diagram obtained from the given information.

From the diagram, 25° is in the first quadrant with all positive values: x = cos25°, y = sin35°

Force for the x and y component: Fx, Fy

250(sin25, cos25) = (250sin25, 250cos25)

= [250(0.4226), 250(0.9063)]

= (105.65, 226.575)

The 250° is in the 2nd quadrant with values: x = cos250°, y = sin250°

Force for the x and y component: (Fx, Fy)

45(sin250, cos250) = (45sin250, 45cos250) = [45(-0.9397), 45(-0.3420]

= (−42.2865, -15.39)

The resultant forces for x and y components = sum of Fx in the 1st and 2nd force and, sum of Fy in the 1st and 2nd force

sum of Fx in the 1st and 2nd force = 105.65 + (−42.2865) = 63.3635

sum of Fy in the 1st and 2nd force = 226.575 + (-15.39) = 211.185

Magnitude = √[(ΣFx)² + (ΣFy)²]

= √[(63.3635)² + (211.185)²]

= √(4014.9331 + 44599.1042)

= √(48614.0373)

= 220.49pounds

Direction = arctan (ΣFx/ΣFy)

= arctan (63.3635/211.185)

= arctan(0.30)

= 16.7°

Total piston displacement is given by the following formula: TT P.D.ED?LN 4 Where P.D. = piston displacement, in cubic inches D
Ede4ka [16]

Answer: ≈ 1696460.03

Step-by-step explanation:

Formula:

P.D.=(\frac{\pi }{4})D^2LN ⇒ \left(\frac{\pi }{4}\right)400^2\cdot 4.5\cdot 6

Steps:

1. calculate pi and inset into equation

=0.785398(400^2)(4.5)(6)

2. calculate exponents

=(0.785398)(160000)(4.5)(6)

3 . multiply the rest

=(125663.706144)(4.5)(6)

=(565486.677646)(6)

4. divide by 2 to get the diameter

=\frac{3392920.065877}{2}

5. round to the nearest hundredth (2 decimal points)

= 1696460.032938 ≈ 1696460.03

Hope this helped!

What is the result of subtracting the second equation from the first -2x+7y=10 3x+7y=2
Iteru [2.4K]

The answer after subtracting the following equation is x= -8/5

Step-by-step explanation:

  • -2x+7y=10 ----- eq(1) , 3x + 7y =2------ eq(2)

  • 7y+3x =2
  • 7y-2x = 10
  • subtracting eq 2 from eq 1 we get
  • 5x = -8
  • x= -8/5
