1 answer:
NISA [10]3 years ago
6 0

Answer:

1. False

2. True

3. True

4. True

5. False

Explanation:

Moment of a force is not a free vector. There are certain quantities along the line with which force is applied.

Force can be moved in any direction along the line of the action without changing the external reaction.

The magnitude of equivalent resultant force is distributed along the centroid point.

The resultant force of a couple force system is zero as it form opposite forces which balances off each other.

A coil of wire 8.6 cm in diameter has 15 turns and carries a current of 2.7 A. The coil is placed in a magnetic field of 0.56 T.
SVEN [57.7K]

Answer:

Explanation:

it is given that diameter = 8.6 cm

radius =\frac{8.6}{2}=4.3\ cm=4.3\times 10^{-2}\ m

current =2.7 ampere

number of turns = 15

area =\pi r^2=3.14\times \left ( 4.3\times 10^{-2} \right )^{2}=0.005806 m^{2}

magnetic field =0.56 T

maximum torque= BINASINΘ  for maximum torque sinΘ=1

so maximum torque==0.56×2.7×0.005806×15=0.13174 Nm

A force of 250 N is acting on an area of 2 m2. The pressure is therefore:
lianna [129]

Answer:

125 Pascal

Explanation:

We know that

Pressure=\frac{Force}{Area}

Applying given values we get

Pressure=\frac{250N}{2m^{2}}

Pressure=125\frac{N}{m^{2}}

Pressure = 125 Pascal
