Answer:
the velocity of the point P located on the horizontal diameter of the wheel at t = 1.4 s is
Explanation:
The free-body diagram below shows the interpretation of the question; from the diagram , the wheel that is rolling in a clockwise directio will have two velocities at point P;
- the peripheral velocity that is directed downward
along the y-axis
- the linear velocity
that is directed along the x-axis
Now;
Also,
where (angular velocity) =
∴ the velocity of the point P located on the horizontal diameter of the wheel at t = 1.4 s is
Answer:
option A
Explanation:
given,
shear force = 425 N
Shear modulus = 1.7 × 10⁹ N/m²
disk equivalent to solid cylinder
height = 0.7 cm and diameter = 6.50 cm
hence, the correct answer is option A
