What is the function of a movable pulley?

The function of a movable pulley is to change the direction of force and save effort. In essence, a movable pulley is a lever with a power arm twice as long as the resistance arm (a labor-saving lever). It not only changes the direction of force but can also save up to half the effort, although it does not save work. More information about pulleys is as follows: Introduction: A fixed pulley is a pulley that does not move. Its immobility is not simply about not moving; rather, the central axis of the pulley is fixed. Advantage: The main advantage of a fixed pulley is that it can change the direction of force. When using a fixed pulley to pull a very heavy object, it may not be easy to apply force directly, but a fixed pulley can redirect the force to a more convenient direction, making it easier to move the heavy object.

What is the most effective method for removing tree sap from a car?

The most effective methods for removing tree sap from a car are: soaking and wiping with alcohol solvent; wiping with soapy water solution; and cleaning with dishwashing liquid, laundry detergent, or laundry liquid to remove the tree sap. Introduction to tree sap: The concept of 'tree sap' on a car is quite broad. In addition to being secretions from trees, it is often the excrement of insects on trees, such as aphids. These small insects specifically suck on tender branches and leaves and then excrete sticky liquid, which is also particularly difficult to clean. Purpose of removing tree sap: It can protect your beloved car from heat and rain, naturally shielding it from tree sap, and also prevent the paint from discoloring due to prolonged exposure to the sun.

Are There Cases Where Running a Red Light Goes Unrecorded?

Running a red light at an intersection will always be captured by cameras. Notification Timeframe for Running a Red Light: If you check at the vehicle management office or traffic police station, you can usually find out the next day; online queries take 3-7 days; if waiting for an SMS notification, it typically arrives within 10 days. Criteria for Determining a Red Light Violation: Electronic eyes capture three photos as evidence: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels passing the opposite stop line. Only when all three photos are present will it be confirmed as running a red light. Common Methods to Check for Red Light Violations: You can check for red light violations via the "Traffic Management 12123" app. After opening the app, log in using your ID card, then locate and click on the traffic violation handling option. Here, you can view your vehicle's current status. If there are any violations, the specific details will be displayed. Visit the service halls of traffic police branches in various districts and counties to check via touch-screen terminals. Log in to the public service websites of local public security traffic management bureaus: find the vehicle violation query section, enter your license plate number and engine number, then click to query.
