olasank [31]

Answer:

hello your question lacks some data and required diagram

G = 77 GPa,  т all = 80 MPa

answer : required diameter = 252.65 * 10-^3 m

Explanation:

Given data :

force ( P )  = 660 -N force

displacement = 15 mm

G = 77 GPa

т all = 80 MPa

i) Determine the required diameter of shaft BC

considering the vertical displacement ( looking at handle DC from free body diagram )

D' = 0.3 sin∅  ,   where D = 0.015

hence ∅ = 2.8659°

calculate the torque acting at angle ∅  of  CD on the shaft BC

Torque = 660 * 0.3 cos∅

             = 660 * 0.3 * cos 2.8659 = 198 * -0.9622 = 190.5156 N

hello attached is the remaining part of the solution

What is static electricity and how does it differ from current electricity
sp2606 [1]

Answer:

1. Static electricity is caused by the build up of electrical charges on the surface of objects, while current electricity is a phenomenon from the flow of electrons along a conductor. 2. When objects are rubbed, a loss and/or gain of electrons occurs, which results in the phenomenon of static electricity.

While in empty space, an astronaut throws a ball at a velocity of 13 m/s. What will the velocity of the ball be after it has tra
aliya0001 [1]
In empty space, there's nothing to exert force on the ball after it leaves
her hand.  It sails away in a straight line, at constant speed of 13 m/s. 
If it doesn't sail too close to a planet, a star, an asteroid, or a moon, it
may travel 6 billion light years and still be moving at 13 m/s.
