Question

Consider a rod of radius R and length L. It is lying along the x-axis of a coordinate system with its left end at the origin. The rod has a non-uniform mass density that varies with position as: ? = ?0(1 + x / L) where ?0 is a constant. a) Make a sketch of ? versus x. What is the value of ? at the end of the rod located at x = 0? What is the value of ? at the other end of the rod located at x = L? b) Calculate the total mass M of the rod. (Hint: M = ? dM = ? ? dV = ? ? A dx where A is the cross sectional area ?R² of the rod)

Consider a rod of radius R and length L . It is lying along the x-axis of a coordinate system with its left end at the origin. The rod has a non-uniform mass density that varies with position as: ρ = ρ0 (1 + x/L) where ρ0 is a constant. a) Make a sketch of ρ versus x . What is the value of ρ at the end of the rod located at x = 0 ? What is the value of ρ at the other end of the rod located at x = L ? b) Calculate the total mass M of the rod. (Hint: M = ∫ dM = ∫ ρ dV = ∫ ρ A dx where A is the cross sectional area πR² of the rod)
