Kan det holde? Hvis din nye og dyre kontorstol går i stykker efter, at du har siddet i den få gange, ville du så købe den samme stol igen, og endda anbefale den til andre? Ved at anvende statik, styrke- og materialelære, når man konstruerer eller ombygger en konstruktion, kan man dimensionere den, så den kan holde til de forventede belastninger, der opstår når produktet anvendes.Dette er den anden bog i trilogien Grundlæggende konstruktion. Trilogien blev udviklet til forfatterens undervisning på Produktionteknolog uddannelse på Københavns Erhvervsakademi. Trilogien er udviklet, så den henvender sig til både ingeniører, arkitekter, maskinmestre, produktudviklere, konstruktører, designere, håndværkere, HTX-studerende og andre, der ønsker at lære eller få genopfrisket, hvordan man beregner styrken i ens konstruktioner.Bogen gennemgår teorien for den grundlæggende styrkelære og er opdelt over fire kapitler: Dimensionering, Profiler, Indre kræfter og Samlinger. Bogen gennemgår gode råd om konstruktion, bevidst svageste led, tyngdepunkt, inertimoment, modstandsmoment, fra kraft til spænding, de forskellige spændingstyper, samt nedbøjning, forskydnings- og momentkurver for simple bjælkekonstruktioner.

'A compelling narrative of the human story' TIM MARSHALL, author of Prisoners of Geography'Lively, rich and exciting... full of surprises' PETER FRANKOPAN, author of The Silk Roads_____________Sand, salt, iron, copper, oil and lithium. They built our world, and they will transform our future.These are the six most crucial substances in human history. They took us from the Dark Ages to the present day. They power our computers and phones, build our homes and offices, and create life-saving medicines. But most of us take them completely for granted.In Material World, Ed Conway travels the globe - from the sweltering depths of the deepest mine in Europe, to spotless silicon chip factories in Taiwan, to the eerie green pools where lithium originates - to uncover a secret world we rarely see. Revealing the true marvel of these substances, he follows the mind-boggling journeys, miraculous processes and little-known companies that turn the raw materials we all need into products of astonishing complexity.As we wrestle with climate change, energy crises and the threat of new global conflict, Conway shows why these substances matter more than ever before, and how the hidden battle to control them will shape our geopolitical future. This is the story of civilisation - our ambitions and glory, innovations and appetites - from a new perspective: literally from the ground up.
