Answer: instateneous center of zero velocity is 0.5m below G and velocities of A and B are 1.949m/s and 2.661m/s respectively.

Explanation:

Calculate the velocity with respect to G

(VBG)

VBG= w × BG

w= 4rad/s

BG= 0.3

VBG= 1.2m/sec

Velocity with respect to G

V AG= w × AG

V AG= 4 × 0.3

=1.2m/s

Use cosine rule to calculate absolute velocity of B

VB= √(VG) ^2+ (VBG)^2- 2(VG) (VBG) cos 110

VB= 2.661 m/s

VA= √(VG) ^2+ (V AG)^2- 2(VG) (V AG) cos 70

=1.949m/s

The point of the intersection of the perpendiculars drawn on VA, VB and VG from A, B and G respectively is instateneous centre of rotation.

GC= VG/w

Where VG is 2 m/sec and w is 4 rad/sec

GC=2/4

GC=0.5 (vertically below G)

Therefore, instateneous center of zero velocity is 0.5m below G and velocities of A and B are 1.949m/s and 2.661m/s respectively.

Seperate real and imaginary parts tan(2x+i3y)
ahrayia [7]

Answer:

First you have to separate real and imaginary parts of Tan(x+iy)=Tan(z)=sin(z)/cos(z)

sinz=sin(x+iy)=sinxcos(iy)+cosxsin(iy)=sinxcoshy-icosx sinhy

cosz=cos(x+iy)=cosxcos(iy)-sinxsin(iy)=cosxcoshy−isinxsinhy

Now if you plug in Tan(z) and simplify (it is easy!) you get

Tan(z)=(sin(2x)+isinh(2y))/(cos(2x)+cosh(2y))= A+iB.

This means that

A=sin(2x)/(cos(2x)+cosh(2y)) and B= sinh(2y)/(cos(2x)+cosh(2y))

Now,

A/B=sin(2x)/sinh(2y)

Identify an object in your house that contains a physical system and list three questions you could use to define the system
jonny [76]

Answer:

ALL CAREFULLY ANSWERED CORRECTLY

Explanation:

1) A loaf of Bread PHYSICAL SYSTEM

✓ How can the environment affect the edibility of the bread

✓ What are the constituents that makes up the bread

✓ What process is involved in these constituents mixing to form the loaf.

2) The law of thermodynamics makes us to understand that when heat/energy passes through a system, the systems internal energy changes with respect to the conservation of energy law. That is energy lost = energy gained. Typically, ice would melt in a cup of hot tea because of the thermal energy in the molecules of the hot tea. When you heat a material, you are adding thermal kinetic energy to its molecules and usually raising its temperature. The temperature of the ice raises due to the kinetic energy added to it and it melts to water.

3) The theory of systems view the world as a complex system of interconnected parts. If we consider the society; (financial systems, political systems, etc) we will agree that they individually have their own components and it's the summation of this components that makes the system, this implies that system thinking could be applicable in this kinda of systems as long as they are made up of components.

4) Technology has boosted every sector of our lives and it has the capacity to do more. Restricting it's importance to entertainment alone would be an underusing of its potentials. Engineering students infact should not need any drive to be encouraged about maximizing all it can do in shaping our world.

5) ~ Nature shows its splendid soul

~Never ceases to leave us in amazement

~And we are in love
