Why steering wheels of heavy vehicles have more radius than light vehicles?

Question

Verified by Toppr

Answer 1

A bigger steering wheels provides more leverage. Trucks are heavier than cars, and it takes more torque to turn the front wheels. The larger steering wheel gives the driver more leverage to operate the steering.

Answer 2

A bigger steering wheels provides more leverage. Trucks are heavier than cars, and it takes more torque to turn the front wheels. The larger steering wheel gives the driver more leverage to operate the steering.

The diagram shows a uniform beam $P Q$ . The length of the beam is $3.0 m$ and its weight is $50 N$ .
The beam is supported on a pivot $1.0 m$ from end $P$ . A load of weight $W$ is hung from end $P$ and
the beam is in equilibrium.
What is the value of $W$ ?

The diagram shows four forces applied to a circular object.
Which row describes the resultant force and resultant torque on the object?

resultant force resultant torque
A non-zero non-zero
B non-zero zero
C zero non-zero
D zero Zero

Five identical bags of rice are balanced on a uniform beam by an object of mass $10 k g$ .
Two more identical bags of rice are added to the other five. The average position of the bags on the beam does not change.
What mass now balances the bags?

The diagram shows an unbalanced rod. Two loads X and Y can be moved along the rod. The rod turns in a clockwise direction as shown. Which action could make the rod balance?
