Ditolong dong kakk, butuh banget :((
kalo bisa pakai cara yaa​

Answer 1

Jawaban:

a. 1.3 m

b. 50/13

Penjelasan:

diket.

W = 500 N

lk = 5 m

F = 130 N

a. lengan beban :

[tex] \frac{w}{f} = \frac{lk}{lb} \\ w \times lb = lk \times f \\ \: \: \: \: \: \: \: \: \: lb = \frac{lk \times f}{w} [/tex]

[tex]lb \: = \frac{5 \times 130}{500} \\ lb = \frac{13}{10} = 1.3[/tex]

b. keuntungan mekanis ( km )

[tex]km = \frac{w}{f} \\ km = \frac{500}{130} \\ km = \frac{50}{13} [/tex]
