If you increased the speed of rotation of the Earth you would get a perceived decrease in the weight of the object due to an increased centrifugal force. 
Increase it fast enough and the momentum of the object will eventually overcome the gravitational pull on it and it will fly off the planet.

The blade of a windshield wiper moves through an angle of 90.08 in 0.40 s. The tip of the blade moves on the arc of a circle tha
oksian1 [2.3K]

Answer:

The centripetal acceleration is 6.95 m/s²

Explanation:

Given;

angular displacement of the blade, θ = 90.08⁰

duration of motion of the blade, t = 0.4 s

radius of the circle moved by the blade, r = 0.45 m

The angular speed of the blade in radian is calculated as;

\omega  = \frac{\theta}{t} \times \frac{\pi \ radian}{180^0} \\\\\omega  =  \frac{90.08 ^0}{0.4 \ s} \times \frac{\pi \ radian}{180^0} \\\\\omega  = 3.93 \ rad/s

The centripetal acceleration is calculated as;

a = ω²r

a = (3.93)² x 0.45

a = 6.95 m/s²

The guy wires AB and AC are attached to the top of the transmission tower. The tension in cable AB is 9.1 kN. Determine the requ
Oksana_A [137]

Answer:

 T_ac = 6.586 KN

R = 10.51 KN

Explanation:

Given:

- Tension in cable T_ab = 9.1 KN

Find:

- Determine the required tension T in cable AC such that the net effect of the two cables is a downward force at point A

- Determine the magnitude R of this downward force.

Solution:

- Compute the three angles as shown in figure attached, a, B , y:

                                 a = arctan (40/50) = 38.36 degrees

                                 B = arctan (50/30) = 59.04 degrees

                                 y = 180 - 38.36 = 82.6 degrees

- Use cosine rule to calculate R and F_ac as follows:

                                 sin(a) / T_ac = sin(B) / T_ab = sin(y) / R

                                 sin(38.36) / T_ac = sin(59.04) / 9.1 = sin(82.06) / R

                                 T_ac = 9.1 * ( sin(38.36) / sin(59.04) )

                                T_ac = 6.586 KN

                                 R = 9.1 * ( sin(82.06) / sin(59.04) )

                                 R = 10.51 KN
