Practical exercise 3: Comparison of the torque for given angle of lap in different types of belts 1.3.1 Aim 1.1.1 To compare the torque for a given angle of contact using different types of belts. 1.1.2 To determine the friction coefficient (u) of a belt. Instruction 1 1. Set up an angle of contact. 2. Mount one of the following pulley belt assembly: > Flat-belt (leather or rope), using flat pulley > V-belt, use badly fitted V-pulley (worn V-pulley) > V-belt, use correctly fitted V-pulley (new pulley) 3. Apply a tension T1 to chosen assembly. 4. Calculate the tension that appears at the other side of the belt (T2) using the following equation: T₂ = (m₁ - (R²) m₂) 9 MOM PRA2 5. Calculate the coefficient of friction (p) using the using the equation: 1₁ = eHe Flat belt T₂ 5. Calculate the coefficient of friction (up) using the using the equation: Flat belt 66 HIG = CHO = euecosec (B) V-Belt 6. Repeat the process from 2 on until the required data of all the pulley- belt assemblies are obtained 1 PRACTICAL EXERCISE 3 T₁ = m₁ x g T₂ Angle of contact is 110⁰ OLD BELT M₁ (kg) 170g 220g 270g 320g 370g R NEW BELT T₁ (N) M₂ (kg) 55g 70g 80g 105g 120g T₂ (N) 220g 270g 320g 370g NEW BELT M₁ (kg) 170g 220g 270g 320g 370g T₁ (N) Additional question 7. plot the graph of T₁ VS T₂ on the same axis 70g 80g 105g 120g M₂ (kg) 70g 90g 110g 120g 160g T₂ (N) Practical exercise 3: Comparison of the torque for given angle of lap in different types of belts 1.3.1 Aim 1.1.1 To compare the torque for a given angle of contact using different types of belts. 1.1.2 To determine the friction coefficient (u) of a belt.
