Final answer:
Foam pads are used on the Scot automatic ripcord release to absorb impacts and protect the mechanism from accidental releases due to sharp blows.
Step-by-step explanation:
The type of pads installed on the main body of the Scot automatic ripcord release to cushion sharp blows are foam pads. These foam pads are intended to absorb impact and protect the mechanism of the release during rigorous activities such as skydiving or airborne operations.
The use of foam is beneficial due to its ability to compress and absorb energy, which can reduce the risk of accidental release triggered by mechanical shocks.
