Answer:
2.17 Mpa
Explanation:
The location of neutral axis from the top will be
Moment of inertia from neutral axis will be given by
Therefore, moment of inertia will be
Bending stress at top=
Bending stress at bottom= Mpa
Comparing the two stresses, the maximum stress occurs at the bottom and is 2.17 Mpa
Answer:
f = 2 Hz
Explanation:
The frequency of a wave is defined as the no. of waves passing per unit of time. Therefore, the frequency of a wave can be calculated by the following formula:
where,
f = frequency of the wave = ?
t = time passed = 1 s
n = no. of waves passing in time t = 2
Therefore,
<u>f = 2 Hz</u>
