The force for pushing or pulling open interior swinging egress doors, other than fire doors, shall not exceed 5 pounds (22 N). These forces do not apply to the force required to retract latch bolts or disengage other devs that hold the door in a closed position. For other swinging doors, as well as sliding and folding doors, the door latch shall release when subjected to a 15-pound (67 N

• #### OT Force required to push a wheelchair up a ramp

15/05/2014· Agree, 200lb person plus 37lb wheelchair, plus a ten pound bag of groceries plus a gallon of milk, say 8 lbs. So 255lb. Static force (just to hold the chair in place) is sin(20°) * 255, or 87lbs force. Using Forrest's number for rolling friction of 0.5%, we get 1.005*87 = 88lbs. Using a coefficient of friction of 0.45 (I've found estimates

• #### Convert Torque, Pound-force foot

Pound-force foot, torque. A pound-foot is a unit of torque (a vector). One pound-foot is the torque created by one pound force acting at a perpendicular distance of one foot from a pivot point. The alternate name "foot-pound" (ft-lb or ft-lbf) is also used to refer to this unit; for example, in the United States, the torque created by automobile engines is usually quoted in foot-pounds. Type

• #### How to Calculate Force Based on Pressure dummies

Pressure and force are related, and so you can calculate one if you know the other by using the physics equation, P = F/A. Because pressure is force divided by area, its meter-kilogram-second (MKS) units are newtons per square meter, or N/m 2. In the foot-pound-second (FPS) system, the units are pounds per square inch, or psi. The unit newtons per square meter is so common in physics that it

• #### How much force/energy is required to lift a 2000lb car

19/08/2015· Since you are not lifting all 2,000 lbs due to the back tires planted on the ground, it will be very hard to find the exact force. During this "lift" your forearm respectively rotates about the elbow. This will be the "hinge point" for the applied force. Lets say the distance from the hinge point to the lift is 12 inches. Say you are lifting 1200 lbs of that car. 12X1200 =14400 in lb. Don't

• #### Pressure & Area to Force Calculator

The relationship between pressure and force is as follows: Pressure = Force / Area. Strictly speaking a kg/cm² is actually kgf/cm². So for a pressure of 1kgf/cm² to produce a 2kg force the surface area would be calculated as follows: Area = Force / Pressure = 2 kgf / 1 kgf/cm² = 2 cm². e.g. If you had a hydraulic ram with a cross sectional
