杆的强度计算杆的特点是细长。各横截面形心的联线为杆的轴线。拉伸(或压缩)、扭转和弯曲,是杆变形的基本形式。强度条件的基本形式为:受力不超过抗力。杆的受力程空可用内力和应力表示。抗
Rod strength calculation rod is characterized by slender. The cross-section of the center of the line of the axis of the rod. Stretching (or compressing), twisting and bending are the basic forms of rod deformation. The basic form of strength conditions: force does not exceed resistance. The force of the rod can be expressed by internal force and stress. anti-
