A steel wire of diameter 1 mm can support a tension of 0.24 kn. suppose you need a cable made of these wires to support a tensio
forsale [732]
Assuming the same deformation and elastic modulus, we can use the relationship:
(P/D)1 = (P/D)2
Where P is the load, Dis the diameter of the wire, 1 is the first wire, and 2 is the second wire. Using the given values and solving for the diameter of the second wire:
D = (24 / 0.24) (1)
D = 100 mm

A disk, initially rotating at 130 rad/s, is slowed down with a constant angular acceleration of magnitude 3.0 rad/s2.(a) How muc
Art [367]

Answer

given,

initially rotating speed = 130 rad/s

final rotating speed = 0 rad/s

constant acceleration = 3 rad/s²

a)  using equation of rotating acceleration

   \omega_f = \omega_i + \alpha t

   0 = 130 - 3 \times t

    3 t = 130    

 t = 43.33 s

time does the disk take to stop is equal to 43.33 s

b) again using equation of rotation

    \theta = \omega_i t + \dfrac{1}{2}\alpha t^2

    \theta = 130\times 43.33 - \dfrac{1}{2}\times 3 \times 43.33^2

    \theta = 2817 rad

angle does the disk rotate during that time is equal to 2817 rad
