Monocoque
The most common form of chassis construction for passenger cars and, ever more so, 4WD cars. Monocoque is French for "Single Shell" and unlike a ladder frame, where the chassis and body are separate for high strength, monococques are specifically designed to crumple in the event of a collision and absorb energy, protecting the occupants from the full force of the crash.

Monocoque vs ladder chassis or unibody vs body on frame respectively. These are the two main types of vehicle chassis. The chassis is the frame or skeleton of the vehicle and here are the two most popular types.Monocoque or Unibody are the terms used to indicate when the body of the vehicle is designed and built to support the weight of the vehicle and any other function of a chassis. This is achieved by strengthening the floor of the vehicle, the pillars and using bracing along various parts of the body.Ladder Chassis or Body over Frame are the terms used when the body of a vehicle is mounted to a separate frame or chassis. This frame is similar to a ladder in design as two long pieces of steel (approximately the length of the vehicle) are held parallel to each other by shorter pieces running across.Either chassis should perform the following functions at least at a workable level.Unibody, body on frame or any type of chassis has to strike a balance between weight/materials used, intended function, vehicle design and cost but the type of chassis used will have certain benefits and ultimately determine the function and character of the vehicle.Performance - The monocoque is a lighter design which is a plus for fuel efficiency, it has more torsional stiffness and is by far the better chassis for performance oriented vehicle. The heavy nature of the ladder chassis makes it tough and it is much better than the monocoque for carrying heavy loads and towing heavier objects.Design - A unibody bodyshell is difficult to design, build and modify (platform sharing) when compared to the body on frame but computer assisted design (CAD) has greatly reduced this advantage. Another body can be placed on a ladder chassis but changes have to be made to major parts of the vehicle.Materials - Unitary bodyshells can be made from a variety of materials steel and steel alloys, aluminium and aluminium alloys and even carbon fiber or combinations of these materials whereas ladder chassis are usually built from steel.Other Benefits - It is much easier to incorporate crumple zones into a vehicle with a monocoque bodyshell but a vehicle with a ladder chassis is much easier to repair after an accident.Monocoque chassis are used in most vehicle types and is more suited for everyday, luxury and sport oriented vehicles but the ladder chassis is better suited for commercial and heavy duty work. Debating on monocoque vs ladder chassis will come down to the intended function of the vehicle.
The difference is that a separate body chassis consists of the vehicle body and a separate frame which the body is bolted to (sometimes referred to as ladder frame). The integral chassis consists of a single body/frame unit, there is no separating them, they are one part (often referred to as unibody construction).
There's no practical difference, it's just how you arrange the numbers.
No. if the floor is smooth you must have friction between the ladder and the floor, or the ladder would just slide away. Technically you could do without friction between wall and ladder, but even that can be helpful in preventing the ladder from going sideways.
because lever is a part of simple machine that makes a ladder have a screw between the both sides of ladder.

Jacobs ladder is a staircase that went to heaven in Jacob's dream. Many believe that the ladder represents the essence of Islam.
That probably refers to the ratio between the length of the ladder, and the distance at which you place the bottom part of the ladder from the wall. If this distance is too short, you have the risk of the ladder falling backwards.
this is a tone ladder. This helpful when teaching music to children, because then they can use the ladder to see that there is a semitone or half step between mi and fa, as well as ti and do.
If the angle between the ladder and the ground is 60 deg, and you know the angle between the ground and the wall is 90 deg, then you have a 30-60-90 degree triangle, which is a common triangle. You should memorize this one. The commonest sides of this right triangle are 4-5-6, with the longest side being the hypoteneuse, in this case the ladder leaning from the ground to the wall. The wall is 4m high, the base of the ladder would be 5m out from the wall, and the length of the ladder is 6m.
a ladder pole strap is a nylon strap used to secure an extension ladder to a utility pole to help avoid "kickout." There are models designed to be used at the base of the ladder (between the 4th and 5th rungs) and those designed to secure the top of the ladder to the pole (or strand). An example of a ladder pole strap would be the Laddermate LM100.
