Question

Jika tongkat diputar di titik C, besarnya momen gaya total adalah?

Answer 1

Verified answer

Dinamika Rotasi
• Momen Gaya

F₁ = 10 N
r₁ = 10 cm = 0,1 m
F₂ = 10 N
r₂ = 10 cm = 0,1 m
F₃ = 10 sin 30° = 5 N
r₃ = 20 cm = 0,2 m

∑ τc = __ ?

∑ τc = τ₁ - τ₂ + τ₃
= F₁r₁ - F₂r₂ + F₃r₃
= (10)(0,1) - (10)(0,1) + (5)(0,2)
= 1 Nm
