A minimum of 10, 75-pound strikes are reported to be the equivalent of over 100 foot pounds, which is why the Grade 1 deadbolt locks have been tested.
How much force does it take to break a door?
Assuming the wooden door is 2 inches thick, 6 feet 8 inches high and 3 feet wide, and is perfectly dry, it would have a breaking force of 1250lbs or 8.61844662MPa, assuming the size of the immovable rod is 2cm diameter and 30cm long, is a perfect and regular dodecagonal prism and does not deform under high pressures.
How much force does it take to open a magnetic door lock?
Though it take 1200lbs to force the lock open, under rated operating conditions, someone could apply more than that by using some sort of lever. It is also possible that the locks are not being used under rated conditions.
How hard is it to break down a door?

Ultimate Lock has the ability to withstand up to 4000 pounds of force, to put things in perspective, most deadbolts can only withstand roughly 100-200 pounds of force.
How much force is needed to break reinforced steel?
For a mild steel door, somewhere around 150 tons or 300,000 pounds. For a hardened steel door, especially made of an exotic alloy like maraging steel, the force could get much higher but would probably stay below 1,000 tons.
Can you force a magnetic door lock?
You can bash down both the maglock and the door with brute force. Assuming you deal enough damage to their barrier’s structure to break them.
How strong is magnetic lock?
Because the mating area of the electromagnet and armature is relatively large, the force created by the magnetic flux is strong enough to keep the door locked even under stress. Typical single door electromagnetic locks are offered in both 600 lbs. (2669 N) and 1200 lbs. (5338 N) dynamic holding force capacities.
What is electric strike lock?
Electric strikes replace a standard door strike and is connected to a power supply. When an electric strike is activated, it releases the latch, unlocking the door. Electric strike locks remain locked from the outside at all times. When the door closes behind you, it automatically returns to a locked position.

How much stronger is reinforced concrete?
You would have a better and more fire resistance when reinforced concrete compared to steel when you home. With that, after building your house, you will never worry about fire. It has a high tensile strength of about nine-tenth of the compressive strength it can exert on the walls after building your house.
How strong is rebar?
Rebar is graded to show the amount of tensile strength it has in terms of pounds per square inch. Grade 33 starts out the low end of strength, with strength increasing as the grade number gets bigger. Grade 40 has a minimum yield strength of 40,000 PSI and a minimum tensile strength of 60,000 PSI.
How much strength does rebar add to concrete?
Rebar that’s off by just an inch can reduce the overall strength of the concrete by 20 percent. That’s why rebar has it’s own inspection. Because it’s very important to the strength of the structure. The ridges you see in rebar help it make a tight bond with the concrete.
What is a Grade 1 deadbolt?
The American National Standards Institute, or ANSI, created deadbolt grades.Grade 1 is the highest quality, and the most dependable deadbolt you can have. Grade 3 is your average deadbolt which will provide an accepted, but minimal, level of security.
