What is Blocks: Definition and 767 Discussions

Code::Blocks is a free, open-source cross-platform IDE that supports multiple compilers including GCC, Clang and Visual C++. It is developed in C++ using wxWidgets as the GUI toolkit. Using a plugin architecture, its capabilities and features are defined by the provided plugins.
Currently, Code::Blocks is oriented towards C, C++, and Fortran. It has a custom build system and optional Make support.
Code::Blocks is being developed for Windows and Linux and has been ported to FreeBSD, OpenBSD and Solaris. The latest binary provided for macOS version is 13.12 released on 2013/12/26 (compatible with Mac OS X 10.6 and later), but more recent versions can be compiled and MacPorts supplies version 17.12.

    Three Blocks force on each other

    Ok, I don't know what I'm really doing in this problem. It does not seem as hard as I am making it seem, but I guess I need help to be guided through it. Here's the problem: Blocks of mass 4, 8, and 12 kg are lined up from left to right in that order on a frictionless surface so each block...

    Friction on two blocks simple help

    OK I was helping a friend with his physics HW but I can't remember for the life of me how to do this. A block of mass 4.0 kg is put on top of a block of mass M = 5.0 kg. To cause the top block to slip on the bottom one, while the bottom one is held fixed, a horizontal force of at least 17 N...

    Three blocks on a fricionless horizontal surface

    OK, three blocks on a fricionless horizontal surface are in contact on each other, a force is applied to block 1, m1, m2, m3, respectively. And m1=m2=m3. how come the force of contact that block one exerts on block is F(m2+m3) / (m1+m2+m3) instead of just F*m2/(m1+m2+m3). ( I know that a is...

    Calculating Buoyant Force: Brain Blocks Pt II

    I have a box when suspended from a cable in a vacuum is 4450N and is .608m wide (it's also a cube). W = 4450N = T1 (tension on the cable) V = 0.2248m^3 When I suspend it into a liquid, L/2 m from the surface, of density 944 kg/m^3, I want to know the buoyant force, the new tension of the...

    I have a couple of brain blocks.

    I've got a U-tube filled with Mercury and water. If I add 11.2 cm of water to the left side, how much does the mercury rise on the right side? For simplicity's sake, D will stand for density, p0 for initial pressure, w = water, m = mercury, h = 11.2 cm for the water and d = the distance the...

    Proof: Numbers with repeating blocks of digits are rational

    Hi everyone, I need to prove that any number with a repeating block of digits is a rational number. Someone told me I should first find a method of constructing a rational number in the form a/b from a number with repeating blocks of digits (and to do it with very 'easy' numbers first). I'm...

    Before I attempt this next problem on sliding blocks

    I'd like to make sure I understand it. It reads... "Two objects, A and B, are placed in contact with each other on a horizontal, frictionless surface. Object A weighs 1.5kg, and B weighs 2.5kg. If a force of 8.0N is exerted on the surface of object A in contact with B AND on the opposite...

    Momentum & Kinetic Energy: Blocks A & B Collide

    In the attached figure, block A of mass 2.0kg slides on a horizontal frictionless table with velocity of 3.0m/s and collides with block B of mass 3.0kg initially at rest on the edge of the table. Block B moves with a horizontal velocity of 2.4m/s, just after the collision. (a) Use...

    How Does Friction Affect the Acceleration of Stacked Blocks?

    A block M1 of mass 16.5 kg sits on top of a larger block M2 of mass 26.5 kg which sits on a flat surface. The kinetic friction coefficient between the upper and lower block is 0.405. The kinetic friction coefficient between the lower block and the flat surface is 0.105. A horizontal force F =...

    How Does Friction Affect Block Acceleration on Different Surfaces?

    For the following problems, I don't know how to start . Please explain every step to me with emphasis on the difference in finding the blocks' acceleration accompanied by the coefficient of friction and the case if it was not present. [I have other problems I need to do.] Find each block's...

    How should you stack the blocks to achieve the maximum protrusion?

    Five identical wood blocks of sides L and thickness H are shifted in one direction to form a leaning tower of the maximum protrusion. How should you stack the blocks to achieve the maximum protrusion? What is the maximum protrusion? What if you had an infinite number of blocks? For any...

    Two blocks and pulley systemhelp on small part

    You got to see the picture 1st. A block of mass m1 = 2 kg rests on a table with which it has a coefficient of friction µ = 0.66. A string attached to the block passes over a pulley to a block of mass m3 = 4 kg. The pulley is a uniform disk of mass m2 = 0.5 kg and radius 15 cm. As the mass m3...

    Two blocks with masses of 4kg and 8kg

    Two blocks with masses of 4kg and 8kg are connected by a string and slide down a 30 degree inclined plane. The coefficient of kinetic friction between 4kg block and the plane is 0.2; that between 8kg block and the palne is 0.35. A) calculate the acceleration of each block. b) calculate teh...
