Answer:
Explanation:
The formula for time period of a pendulum is given as follows :
T = 2π
l is length of pendulum and g is acceleration due to gravity .
So time period of pendulum is not dependent on the mass of the pendulum . If time period is same and length is also the same then acceleration due to gravity will also be the same . Hence the acceleration due to gravity at distant planet will be same as that on the earth.

Answer:
The tension on the shank is
Explanation:
From the question we are told that
The strain on the strain on the head is
The contact area is
Looking at the first diagram
At 600 MPa of stress
The strain is
At 450 MPa of stress
The strain is
To find the stress at we use the interpolation method
Substituting values
Generally the force on each head is mathematically represented as
Substituting values
Now the tension on the bolt shank is as a result of the force on the 6 head which is mathematically evaluated as
