Two strips of metal are riveted together at their ends by four rivets, each of diameter 6 mm. Assume that each rivet is to carry one quarter of the load. If the shearing stress on the rivet is not to exceed `6.9xx10^7Pa`, the maximum tension that can be exerted by the riveted strip is

Explanation

To find the maximum tension that can be exerted by the riveted strip, we can follow these steps:

### Step 1: Determine the area of one rivet
The area \( A \) of a rivet can be calculated using the formula for the area of a circle:
\[ A = \pi r^2 \]
where \( r \) is the radius of the rivet.
