The correct Answer is:
To determine the direction of the friction force exerted by the truck on the crate, we can follow these steps:
### Step 1: Understand the Situation
The crate is on a flatbed truck that is accelerating to the east. Since the crate is not sliding, it is moving along with the truck.
**Hint:** Consider the relationship between the motion of the truck and the crate.
### Step 2: Identify the Forces Acting on the Crate
When the truck accelerates, there are two main forces acting on the crate: the gravitational force pulling it down and the frictional force that acts between the crate and the truck's surface.
**Hint:** Think about how friction works to prevent sliding.
### Step 3: Determine the Direction of Acceleration
The truck is accelerating to the east. For the crate to move with the truck without sliding, it must also accelerate in the same direction.
**Hint:** Remember that friction always acts in the direction that prevents relative motion.
### Step 4: Analyze the Role of Friction
Friction is the force that prevents the crate from sliding off the truck. Since the truck is accelerating to the east, the friction force must act in the same direction to keep the crate moving with the truck.
**Hint:** Consider what would happen if there were no friction.
### Step 5: Conclude the Direction of the Friction Force
Since the truck is accelerating to the east and the crate is not sliding, the friction force exerted by the truck on the crate must also be directed to the east.
**Hint:** Friction acts to oppose relative motion, so it must act in the direction of the truck's acceleration.
### Final Answer
The direction of the friction force exerted by the truck on the crate is to the east.
To determine the direction of the friction force exerted by the truck on the crate, we can follow these steps:
### Step 1: Understand the Situation
The crate is on a flatbed truck that is accelerating to the east. Since the crate is not sliding, it is moving along with the truck.
**Hint:** Consider the relationship between the motion of the truck and the crate.
### Step 2: Identify the Forces Acting on the Crate

What is the direction of frictional force actiog on a body moving or sliding towards east ?
Two thin circular disks of mass 2kg and radius 10 cm each are joined by a rigid massless rod of length 20 cm. the axis of the rod is along the perpendicular to the planes of the disk through their centres. This object is kept on a truck in such a way that the axis of the object is horizontal and perpendicular to the direction of the motion of the truck. Its friction with the floor of the truck is large enough so that the object can roll on the truck without slipping. Take x axis as the direction of motion of the truck and z-axis as the vertically upwards direction. if the truck has an acceleration of 9m//s^2 Calculate: (i) The force fo friction on each disk, (ii) The magnitude and the direction of the frictional torque acting on each disk about the centre of mass O of the object. Express the torque in the vector form in terms of unit vectors hati, hatj and hatk in the x,y, and z directions.
