Masonry in foundaion and plinh. Masonry in supersrucure 3. Plasering work 4. Poining. e iscuss he facors affecing he srengh of imber.. f riefly describe he various defecs in bricks.. g riefly explain he processes involved in he manufacure of bricks in order.. a compound bar consiss of a circular rod of seel of diameer 5, rigidly fied ino a copper ube of inernal diameer 5 and hickness.5. If he bar is subjeced o an axial load of 00k, find he sresses developed in he wo maerials. Given: 5 0 / and 5. 0 /. s c. b circular log of imber has diameer. eermine he dimension of he sronges recangular secion, one can cu from his log.. c raw he bending momen and shear force diagrams for overhanging beam shown in he figure below. Indicae he significan values including he poin of conraflexure. m 60k oal riangular load 0k C. d solid shaf ransmis 50kW a 00rpm. If he shear sress is no o exceed 75, wha should be he diameer of he shaf?
