1. Determine the consistent-mass matrix for the one-dimensional bar discretized into two elements as


1. Mention the consistent-magnitude matrix for the one-dimensional bar discretized into two elements as shown in Figure P16–1. Let the bar own modulus of elasticity E, magnitude inobservance r, and cross-sectional area A.

2. For the one-dimensional bar discretized into three elements as shown in Figure P16–2, mention the lumped- and consistent-mass matrices. Let the bar properties be E; r, and A throughout the bar.
