Types of Belt Drives Quiz

V-belts are usually used for which type of drives?

• Long drives

• Short drives

• Medium drives

• None of these

What is the advantage of V-belt drive over flat-belt drive?

• Noiseless drive

• Higher velocity ratio

• Used for smaller center distance

• All of the above

If T1 and T2 are the respective tensions on the tight and slack side of the open belt drive, then the power transmitted by the belt drive is given by:

• P = (T1 - T2)v

• P = (T1 + T2)v

• P = (T1 - T2)/v

• P = (T1 + T2)/v

V-belts get their name because of:

• Their power transmission direction

• Their dimensions

• Their V-shaped cross section

• Their appearance

Vee-belt E-type cross-sections are generally used in:

• Automobiles

• Small Engines

• When driver and driven units are far off

• Heavy duty machine

In a belt drive system, when the speed of the belt increases, what happens to the power transmitted?

• Power transmitted will decrease

• Co-efficient of friction decreases

• Co-efficient of friction increases

• Power transmitted will increase

In a pulley and belt drive, if m is mass of belt per unit length, the velocity of belt for maximum power transmission is equal to:

• √(T/3m)

• √(2T/m)

• √(T/2m)

• √(T/m)

If there is no slip in the transmission, what is the equation for the velocity ratio in the open belt drive?

• N1/D1 = N2/D2

• N1/N2 = D2/D1

• N1/D1 = D2/N2

• None of these

In which condition is maximum power transmitted in a belt drive?

• Tmax = 0.5Tc

• Tmax = 3Tc

• Tmax = Tc

• Tmax = 2Tc

What is the primary function of a belt in a belt drive system?

• To transmit power

• To support weight

• To reduce friction

• To increase speed
