Conceptual Quiz on Single Fixed Pulley | CBSE NCERT Class IX | #exam #education

A single fixed pulley changes the direction of the ___ without changing its magnitude. What is the ideal mechanical advantage (MA) of a single fixed pulley? In a single fixed pulley, if a load of 50 N is lifted, what is the required effort in an ideal system? Where is the axle of a single fixed pulley attached? What type of lever does a single fixed pulley closely resemble? A single fixed pulley multiplies the input force to make lifting heavy objects easier. In an ideal single fixed pulley, the distance the effort moves is equal to the distance the load moves. The velocity ratio (VR) of a single fixed pulley is always 1. In a real-world single fixed pulley, the actual efficiency is less than 100%. A single fixed pulley can be used to lift a load upwards by pulling the rope upwards. What is the velocity ratio (VR) of a single fixed pulley? If a real single fixed pulley has an efficiency of 80%, what is its mechanical advantage (MA)? An effort of 60 N is used to lift a 48 N load with a fixed pulley. Calculate its efficiency as a decimal. If you pull the rope of a single fixed pulley down by 5 meters, how many meters does the load rise? A single fixed pulley allows you to use your own ___ to help lift a load downward. In a single fixed pulley, the tension throughout an ideal string is ___. When a load is suspended at rest by a single fixed pulley, the upward tension equals the downward ___. The mechanical advantage of a real-world fixed pulley is always less than ___. Arrange the following steps in order to calculate the efficiency of a real fixed pulley system where Load = 40N and Effort = 50N. Arrange the components of a single fixed pulley system from the overhead support downwards to the load.
