Belt Drive TOM(U-5, P-1)

The ratio of tension of two sides of a flat belt is given by

• -e^(-μ×θ)

• e^(μ×θ)

• e×μ×θ

• None of the above

Crowning of a pulley is done to

• Prevent the slipping of a belt

• To increase the tension of a belt

• To increase the angle of contact

• None of the above

The power transmitted by a belt drive is (T1=Tension on tight side, T2=Tension on slack side, where v = linear velocity, ω = angular velocity)

• (T1-T2) x v

• (T1-T2) x ω

• (T1-T2) / v

• (T1-T2) / ω

The initial tension (T0) in a belt is given by

Where T1=Tension on tight side of belt drive

T2=Tension on slack side of belt drive

• T0 = (T1-T2)/2

• T0 = (T1+T2) /2

• T0 = (T1-T2) x 2

• T0=(T1+T2) x 2

In which of the following drives, there is no slip

• Open belt drive

• Crossed belt drive

• Rope drive

• Chain drive
