bantuin jawab yah kakak

# Tinjauan papan,

T1 + T2 = 10•9,8
T1 + T2 = 98 ..... (1)

Jika T1 : T2 = 3 : 4,
maka
T1 = (3/7)•98 = 42
dan
T2 = (4/7)•98 = 56 

# Tinjauan alumunium, 
Syarat setimbang 
Στ = 0

T•1,5•sin@ - T1•(0,25) - 2,5•9,8•(0,75) - T2•(1,25) = 0

400•1,5•sin@ - 42•(0,25) - 24,5•(0,75) - 56•(1,25) = 0

600•sin @ - 10,5 - 18,375 - 70 = 0

600•sin @ - 98,875 = 0

Sin @ = 98,875 / 600

Sin @ = 0,1648

@ = 9,485°


Step 2 
-------
Lihat segitiga, 

Tan @ = h/L

h = L. Tan @

h = 1,5 Tan 9,485°

h = 1,5• 0,167

h = 0,251 m
