固体压强计算题 2 随堂 练习 1(小明同学在探究“压力的作用效果与压力 大小的关系”时，做了如下图甲、乙所 示的实验。 (1)实验能够得到的结论 是 。 (2)若想继续探究“压力的作用效果与受 力面积大小的关系”，应再做图 _______(填“丙”或“丁”)所示实 验。 Pu ash must not exceed 1500mm. Block in place and more are: block, should be watered before rushing to dust, clear blocks debris on the surface of the rear handle. During handling and transport of aerated concrete blocks, throws and dumping is strictly prohibited, after entering varieties and specifications, respectively a tidy, stacking height should not be more than 2m. Aerated concrete blocks to prevent rain. When each layer of masonry, from the corner or anchor blocks, starting at the crane masonry skin, correct skin, Pi Pila control elevation of masonry and wall flatness. Vertical filling mortar: each building block, in place after the correction, filling Vertical joints with mortar, followed by joint seam (puree jointing), depth of General 3--5mm. When masonry masonry adjacent to the near boards, beams, masonry is heavy (about 7 days) with sliced work lower after masonry between the upper plate beam and used ordinary clay bricks to tight filling, mortar full tilt of about 60 ?. Masonry body and cut force wall Zhijian of gap with mortar fill, and squeeze real, gray sewing cross flat vertical, level gray sewing should be control in 15mm around, but not is less than 10MM, not is greater than 20mm, level gray sewing of full degrees shall not below 80%, vertical to gray sewing should be control in 20mm around, but not is less than 15mm, not is greater than 25mm, vertical sewing shall not appeared transparent sewing. Infilled beams according to the building plans of opening hole in lintel Universal Atlas use. Load levels, the design requirements, when the hole close to the shear walls, beams using in-situ construction, concrete shear walls, according to relevant standard specification for anchorage. By design requirements set structure column, 2(置于水平地面上的石柱，高为0.4m，横截 2面积为0.15m，质量为150kg，g取 10N/kg(求: (1)石柱的重力; (2)石柱的密 度; (3)石柱对
