Hoist: Force and Tension

What is the relationship between force and tension in hoisting?

• Tension in the lifting cable increases the force applied to the hoist

• Tension in the lifting cable reduces the force applied to the hoist

• Force and tension are unrelated in hoisting

• Force applied to the hoist is converted into tension in the lifting cable or rope.

Explain how the angle of the hoist affects the tension in the rope.

• The tension in the rope decreases as the angle of the hoist becomes more acute.

• The tension in the rope remains constant regardless of the angle of the hoist.

• The tension in the rope increases as the angle of the hoist becomes more acute.

• The tension in the rope is not affected by the angle of the hoist.

If a hoist is lifting an object with a mass of 500 kg, and the acceleration due to gravity is 9.8 m/s^2, what is the force exerted by the hoist?

• 4900 N

• 9800 N

• 500 N

• 2450 N

How does the weight of the object being lifted affect the tension in the hoisting rope?

• The tension in the hoisting rope remains the same

• The tension in the hoisting rope decreases

• The tension in the hoisting rope causes the object to fall

• The tension in the hoisting rope increases

What are the factors that can affect the force required for hoisting an object?

• Size of the hoisting machine, brand of the hoisting machine, color of the hoisting machine, and distance from the equator

• Color of the object, temperature of the environment, type of material, and time of day

• Weight of the object, angle of the hoist, friction, and efficiency of the hoisting mechanism

• Number of people operating the hoist, type of music playing in the background, time of year, and smell of the object being hoisted

Explain the concept of mechanical advantage in hoisting.

• The force exerted by the hoist on the load

• The distance the load is lifted

• The speed at which the hoist operates

• Ratio of the load force to the effort force

What safety measures should be taken into consideration when dealing with hoisting operations?

• Ignoring weight limits and load calculations

• Wearing casual clothing during hoisting operations

• Proper training, regular equipment inspections, appropriate rigging equipment, adherence to weight limits and load calculations

• Using damaged or worn-out rigging equipment

Describe the role of friction in hoisting and its impact on force and tension.

• Friction decreases the force and tension required to lift an object.

• Friction has no impact on force and tension in hoisting.

• Friction only impacts the speed of hoisting, not the force and tension.

• Friction increases the force and tension required to lift an object.

How does the length of the hoisting rope affect the tension when lifting an object?

• The tension increases

• The tension becomes zero

• The tension remains the same

• The tension decreases
