Applying Statistic science and Tension Applying Tension Theory on Building Construction By : SMK NEGERI 5 SURAKARTA

Goals Student can understand tension theory. Student can apply tension theory on Building Construction. Teknologi dan Rekayasa

Tension Theory Tension is : load which is recetved by each width unitof surface , if on a parts of an object which has width of the surface F cm2 which operate a force of p kg, so the force will be continued to along of the stem. Teknologi dan Rekayasa

Tension Theory Working load which operate in an objec : - pulling load - pressing load - shifting load, etc. Teknologi dan Rekayasa

Tension theory Kinds of tension which is happening : - pulling tension - pressing tension - shifting tension, etc. Teknologi dan Rekayasa

Tension Theory on building Construction a. Pulling tension is tension which happened on an object , if outer force which work on an object is pulling force. P σtr = kg/cm2 F Teknologi dan Rekayasa

Tension Theory on Building Construction Pulling tension P A B Teknologi dan Rekayasa

Tension Theory on Building Construction b. Pressing tension is a tension which is happened in an object , if outer force which works on a part of an object is a pressing force. P σd = kg/cm2 F Teknologi dan Rekayasa

Tension Theory on Building Construction Pressing tension P A B Teknologi dan Rekayasa

Tension Theory on building Construction c. Shifting tension is tension which happened adalah tegangan yang terjadi bila gaya luar yang bekerja menimbulkan gaya geser pada suatu bagian benda itu. P ζgs = kg/cm2 F Teknologi dan Rekayasa

Tension Theory on Building Construction Shifting tension P P1 F Teknologi dan Rekayasa

Tension Theory on Building Construction d. Twisting theory is tension which is happened if on a part of an object (stem) works twisting moment , so that on the layers of the stem happened pulling tension and pressing tension. M1 σl = kg/cm2 W1 Teknologi dan Rekayasa

Tension Theory on Building Construction Twisting tension P A B a Batang dibebani pada lengkung Teknologi dan Rekayasa

Tension Theory on Building Construction Bent tension A B The stem is loaded on curve. Teknologi dan Rekayasa

Tension Theory on Building construction e. Twisting tension is tension which happened where its surface stand erectly against stem ace. MP ζP = kg/cm2 WP Teknologi dan Rekayasa
