Question

N-mg*cos(a)-f*sin(a)=0. выразить n​

Answer 1

Перебросим всё вправо, кроме N.

n=mg*cos(a)+f*sin(a)

Answer 2

To express n in terms of other variables, let's rearrange the equation:

n - mgcos(a) - fsin(a) = 0

We can isolate the variable n by adding mgcos(a) and fsin(a) to both sides:

n = mgcos(a) + fsin(a)

Therefore, the expression for n is n = mgcos(a) + fsin(a).
