Final answer:
Dowels should be placed at points of load concentration or potential differential movement to ensure adequate and uniform load transfer.
Step-by-step explanation:
In engineering, dowels are used to transfer load between structural elements. To ensure adequate and uniform load transfer, dowels should be placed at the points where load is concentrated or where there is a potential for differential movement.
For example, in concrete construction, dowels are often used to transfer loads between slabs or walls. They are typically placed at expansion joints, construction joints, or areas of high stress.
Proper placement of dowels helps to distribute the load evenly and prevent cracking or failure of the structural elements.
