Praktikan Titis Rizki Bella Risha Mukti

Mb (kg) 45 54 50 39 43

Wb(N) 450 540 500 390 430

L1 (m) 0,93 0,97 0,95 0,94 0,87

L2 (m) 1,09 1,2 1,07 1,08 1,02

h (m) 0,46 0,51 0,51 0,49 0,47

Keterangan : Mb = massa badan (kg) Wb = berat badan (N) L1 = jarak antar pusar sampai telapak kaki (m) L2 = jarak posisi push up antara telapak tangan penopang sampai telapak kaki (m) h = ketinggian rata-rata terangkat tubuh (m) L3 = jarak pusar sampai bahu g = 9,8 m/s2

L3 (m) 0,16 0,23 0,12 0,14 0,15

Analisis Data 1. Praktikan 1 (Titis) a. Gaya oleh tangan ΣƮ = 0 (Wb . L1) – ( Ft . L2) = 0 (Wb . L1) = ( Ft . L2) Ft = Wb x

L1 L2

0,93 Ft = 450 x 1,09 Ft = 383,94 N b. Gaya Oleh Kaki ΣƮ = 0 (Wb . L3) – ( Fk . L2) = 0 (Wb . L3) = ( Fk . L2) Fk = Wb x

L3 L2

0,16 Fk = 450 x 1,09 Fk = 66,06 N c. Usaha W = Ft . h W = 383,94. 0,46 W = 176,61 cm Pembuktian : W = Ft + Fk W = 383,94 + 66,06 W = 450 N 2. Praktikan 2 (Rizki) a. Gaya oleh tangan ΣƮ = 0 (Wb . L1) – ( Ft . L2) = 0 (Wb . L1) = ( Ft . L2) Ft = Wb x

L1 L2

0,97 Ft = 540 x 1,20 Ft = 436,5 N

b. Gaya Oleh Kaki ΣƮ = 0 (Wb . L3) – ( Fk . L2) = 0 (Wb . L3) = ( Fk . L2) Fk = Wb x

L3 L2

0,23 Fk = 540 x 1,20 Fk = 103,5 N c. Usaha W = Ft . h W = 436,5. 0,51 W = 222,615 cm Pembuktian : W = Ft + Fk W = 436,5 + 103,5 W = 540 N 3. Praktikan 3 (Bella) a. Gaya oleh tangan ΣƮ = 0 (Wb . L1) – ( Ft . L2) = 0 (Wb . L1) = ( Ft . L2) Ft = Wb x

L1 L2

0,95 Ft = 500 x 1,07 Ft = 443,925 N b. Gaya Oleh Kaki ΣƮ = 0 (Wb . L3) – ( Fk . L2) = 0 (Wb . L3) = ( Fk . L2) Fk = Wb x

L3 L2

0,12 Fk = 500 x 1,07 Fk = 56,075 N c. Usaha

W = Ft . h W = 443,925. 0.51 W = 226,402 cm Pembuktian : W = Ft + Fk W = 443,925 + 56,075 W = 500 N 4. Praktikan 4 (Risha) a. Gaya oleh tangan ΣƮ = 0 (Wb . L1) – ( Ft . L2) = 0 (Wb . L1) = ( Ft . L2) Ft = Wb x

L1

W = Ft + Fk W = 339,444 + 50,556 W = 390 N 5. Praktikan 5 (Mukti) a. Gaya oleh tangan ΣƮ = 0 (Wb . L1) – ( Ft . L2) = 0 (Wb . L1) = ( Ft . L2) Ft = Wb x

L1 L2

0,87 Ft = 430 x 1,02 Ft = 366,765 N

L2

0,94 Ft = 390x 1,08 Ft = 339,444 N

b. Gaya Oleh Kaki ΣƮ = 0 (Wb . L3) – ( Fk . L2) = 0 (Wb . L3) = ( Fk . L2)

b. Gaya Oleh Kaki ΣƮ = 0 (Wb . L3) – ( Fk . L2) = 0 (Wb . L3) = ( Fk . L2)

Fk = Wb x

Fk = Wb x

L3

L3 L2

0,15 Fk = 430 x 1,02 Fk = 63,235 N

L2

0,14 Fk = 390 x 1,08 Fk = 50,556 N c. Usaha W = Ft . h W = 339,444 . 0,49 W = 166,327 cm Pembuktian :

c. Usaha W = Ft . h W = 366,765. 0,47 W = 172,38 cm Pembuktian : W = Ft + Fk W =366,765 + 63,235 W = 430 N
