How to calculate the maximum lifting force

1. People can provide the greatest upward force

2. (1) His maximum lifting force is 250 * 10 = 2500n
(2) the weight of the object the athlete can lift on the moon is 2500 * 6 / 10 = 1500kg

3. The maximum pulling force of human is equal to the gravity of human
because when the pulling force of human is equal to the gravity of human, the pulling force of rope is also equal to the gravity of human
there is no supporting force of the ground, that is, human leaves the ground
so the pulling force of human will not increase any more

the maximum lifting force is unknown, which should have nothing to do with the maximum pulling force and the gravity of human

4. No matter how powerful it is, it can't be lifted up unless it has the aid of foreign objects

5. How can not sell, very simple, Taobao has already banned the release of such virtual goods.

6. Open Taobao - seller center
- open a shop immediately
it's best to do real things

7. The lifting force itself is constant, just like a person running against the wind, along the wind or a train running at a constant speed, the speed changes to the speed relative to the ground. The reason why we calculate the resultant force is that when the object accelerates up or down, what we lift is not the gravity of the object itself. We also need to add or subtract the force proced by our lifting force on the speed change of the object. For example, in total weightlessness, it's not a problem for people to lift tanks.

8. Each horsepower can theoretically proce 8 kg of lift; You can calculate it on the basis that one horsepower can increase the weight by 5 kg. Determine the maximum lift coefficient
the maximum lift coefficient depends on the wing geometry, airfoil, flap geometry and its span, leading edge slat and slat geometry
shape, re number, surface finish and the influence from other aircraft components, such as fuselage, engine nacelle or pylon. The trim force provided by the tail will increase or decrease the maximum lift, depending on the direction of the trim force. If the propeller wash or jet wash impinges on the wing or flap, the maximum lift will also be greatly affected under the working condition of the engine
most aircraft use different flap states ring takeoff and landing. During landing, the flaps are deflected to the maximum position to
provide maximum lift and drag. However, the maximum flap deflection angle for take-off may cause more drag than is expected for rapid acceleration and climb. Therefore, the flap at this time will use about half of the maximum deflection angle, so that the maximum lift coefficient at landing will be larger than that at
takeoff. Generally, the maximum lift coefficient of takeoff is about 80% of that of landing.

The so-called MBO (management by objective) refers to the modern management method which takes the goal as the guidance, takes the performance as the standard, takes the plan as the bridge, takes the task as the footprint to realize the goal, and makes the organization and the indivial achieve the best performance

The popular way of MBO is responsibility system: let all members of an organization actively participate, determine the work objectives from top to bottom, and implement & quot; Self control & quot& quot; Self motivation;, A method system to ensure the realization of goals from the bottom up

target management is closely related to plan management, task management, log management and performance management: target is the first, there are goals first, then performance is set, then there are plans, and then there are task execution, log feedback task execution, performance appraisal feedback target plan task execution. The key points in this process are: A. reasonable performance system; B. Task management is effective

the weak executive ability of enterprise employees is mostly caused by unclear goal setting: clear and quantitative goal, long-term goal and flexible change, goal participation, goal monitoring...

OA system integrates goal management with business scenarios, and uses "decentralized management and maintenance", "specific responsibility" and "Feedback tracking automation" makes the goal more than just a slogan

(management by objectives)

objective definition and quantification: the OA system objective management mole adopts the "onion peeling method", decomposes the company's strategic objectives according to the organization and time dimensions, and publishes them on the unified execution platform, clarifies post responsibilities, and ensures that indivial efforts and results are consistent with the company's expectations

flexible and changeable objectives: the long-term strategic objectives of the company can be maintained by special personnel, and the specific objectives of employees can be assigned to indivial self-management to achieve decentralized management and meet the needs of long-term and flexible changes of objectives

goal whole process monitoring: in order to make managers clearly grasp the goal dynamics of each person in the team, the platform supports relevant personnel to conct timely feedback and exchange, automatically import data, and automatically sort out statistical analysis charts according to the organization and time maintenance execution, so as to provide basis for enterprise assessment

Objective management of OA system is helpful to grasp the fate of enterprises, maintain the balance between long-term and short-term interests, and provide direction and path to enhance the executive power of enterprises
