Body a, weighing = 8kg, is placed on a rough surface, and a thread is tied to it thrown over the block. what kind of load should be tied to the end so that the coefficient of friction is 0.4
According to Newton’s second law:
Frav. = ma;
On the OX axis:
F = Ftr. since a = 0
On the OA axis:
N = mg;
Since Ftr. = МN, and F = mloadg, then
mload = Mm, mload = 3.2kg
