Respuesta:
4,4271 cm = r
Explicación:
F = 400 N
M1 = 200 kg
P = F2 = 200 * 9,8 = 1960 N
d = 4 cm
r = 2 cm
A1 = Pi * 2^2
A1 = 12,56 cm^2
400 N / 12,56 cm^2 = 1960 N / A2
31,8471 N/cm^2 = 1960 N / A2
A2 = 1960 N / 31,8471 N/cm^2
A2 = 61,544 cm^2
61,544 cm^2 = Pi * r^2
61,544 cm^2 / Pi = r^2
19,6 = r^2
